Landuse change and hydrologic processes: Ajax Architecture Implementation Techniques Abstract: Today's rich Web applications use a mix of Java Script and asynchronous communication with the application server. This mechanism is also known as Ajax: The intent of Ajax is to exchange small pieces of data between the browser and the application server, and in doing so, use partial page refresh instead of reloading the entire Web page.
However, AJAX combines these technologies to let Web pages retrieve small amounts of data from the server without having to reload the entire page. This capability makes Web pages more interactive and lets them behave like local applications. Many new and extremely popular Web applications have been introduced such as Google Maps, Google Docs, Flickr, and so on.

Composite materials are ideal for aerospace applications due to their high strength to weight ratio and their excellent fatigue resistance. Fiber reinforced Composite is widely used in light weight structures for different applications.
The main properties that describe a composite material are the engineering constants and the strength properties of a single unidirectional lamina that make the laminated structure. The experimental evaluation of these properties is quite costly and time consuming because they are functions of several variables such as the individual constituents of the composite, fiber volume fraction, packing geometry and fabrication processes.
Hence, analytical models to predict these properties were developed by researchers to aid the design of composites. In recent years numerous failure theories have been proposed and are available to the composite structural designer. Object of this review is to gather the available guide lines for theoretical models of failure analysis of fiber reinforced Composite.
Tao, Purdue University, D. Fault studies are important power system analysis for stable and economical operations of power systems. Faults are categorised as symmetrical and unsymmetrical.
In this paper, three-phase symmetrical fault is simulated using the Nigerian Bus, kV Transmission Grid. Two different MatLab based programmes were developed; one program was for Load Flow Studies which determines prefault conditions for the power system based on Newton-Raphson method. The other program determines fault current magnitudes for threephase short-circuit on the power system.
The information gained from the fault studies can be used for proper relay select Key words: Reference  Muhammad, Aree A. Chand and Company Ltd. Investment in inventory absorbs a large portion of the working capital of a company and often it represents a large portion of the total assets of a business.
By improving return on investment by increasing the rate of inventory turnover, management often wants to ensure economic efficiency. Effective inventory management enables a firm to provide lower costs, rapid response and flexibility for its customers. Just-in-time JIT philosophy is most widely adopted and practices in the recent years worldwide. It aims at reducing total production costs by producing only what is immediately needed and eliminates wastes.
It is based on a radically different concept, deviating substantially from the existing manufacturing practices in many respects. It is a very effective tool to reduce the wastage of inventory and manage it effectively.
It has the potential to bring substantial changes in the existing setup of a company; can give it a new face, broaden its acceptability and ensure a longer life. It can strategically change the atmosphere needed for longer survival. The new outlook acquired by the company can meet global expectations of the customers. JIT happens to provide global markets. The present paper examines the strategic role of JIT in inventory management.
Information technology helps JIT in managing inventory effectively, as it helps in integrating the components of supply chain network. Quality aspect of inventory management has also been discussed. Getting control of just-in-time, Harvard Business Review, pp. Ward, P May L and Peterson, L.

For this purpose, compact fluorescent lamps, incandescent lamps, and electric heaters were chosen as single phase loads. The study was performed by adopting a full range of response surface methodology using Box—Behnken experimental design to express the net harmonic current 3rd and 5th as an empirical model.
The model provided an excellent explanation of the relationship among the number of loads and the net harmonic currents. Contour graphs of some of the harmonic currents was plotted to show the interactions clearly and to discuss the results of model in the graphic detail. The results of experiments showed that the harmonic interaction between the loads can be defined as a regression model which is statistically significant.

Comparison of Interestingness Measures: Data Mining is considered to be a step of paramount importance in the process of Knowledge Discovery in Databases.
The term "Interestingness Measure" unequivocally forms a very essential aspect of extraction of "interesting" rules from databases. As there are a huge number of association rules or patterns that are generated by most Association Rule Mining Algorithms, there arises a need to prune away the unnecessary and unwanted rules.
The rules that are crucial and indispensable can therefore be presented to the end user based on the application of these "Interestingness Measures". The reason this is done is so that the user gets a narrow focus on only those rules that will provide better business understanding and intelligence. However, there are a plethora of measures available today, and selecting the best amongst them requires a thorough research on each of them. This paper therefore provides a comparative study of certain important measures, thereby highlighting which measure is apt for application in which situation.

With increase in image depth , roughness increases in case of man-made structures whereas natural scene images become smooth, thus reducing the local roughness of the picture. Such kind of specific arrangement produces a particular spatial pattern of dominant orientations and scales that can be described using Gabor filter as it gives the local estimate of frequency content in an image.

Its properties like low cost, high bandwidth and significant progress has been made in understandingthe behavior of TCP and congestion-controlled traffic over CSMA based multihop wireless networks. Despite these advances, however, no prior work identified severe throughput imbalances in the basic scenario of mesh networks, in which a one-hop flow contends with a two-hop flow for gateway access.
In this paper, we demonstrate via real network measurements, testbed experiments, and an analytical model that starvation exists in such a scenario; i. Our analytical model yields a solution consisting of a simple contention window policy that can be implemented via standard mechanisms defined in IEEE Despite its simplicity, we demonstrate through analysis, experiments, and simulations that the policy has a powerful effect on network-wide behavior, shifting the network's queuing points, mitigating problematic MAC and transport behavior, and ensuring that TCP flows obtain a fair share of the gateway bandwidth, irrespective of their spatial location.
Higher-Speed Physical Layer Extension in the 2. The electrocardiogram ECG is widely used for diagnosis of heart diseases. Good quality of ECG is utilized by physicians for interpretation and identification of physiological and pathological phenomena.
However, in real situations, ECG recordings are often corrupted by artifacts. Noise severely limits the utility of the recorded ECG and thus need to be removed, for better clinical evaluation.
Donoho and Johnstone [4, 5, 10] proposed wavelet thresholding denoising method based on discrete wavelet transform DWT with universal threshold is suitable for non-stationary signals such as ECG signal. In the present paper a new thresholding technique is proposed for de-noising of ECG signal. This new de-noising method is called as improved thresholding de-noising method could be regarded as a compromising between hardand soft-thresholding de-noising methods.
The advantage of the improved thresholding de-noising method is that it retains both the geometrical characteristics of the original ECG signal and variations in the amplitudes of various ECG waveforms effectively. The experimental results indicate that the proposed method is better than traditional wavelet thresholding de-noising methods in the aspects of remaining geometrical characteristics of ECG signal and in improvement of signal-tonoise ratio SNR.

The construction industry in recent years has incorporated information technology which serves to facilitate the conceptualization and realization of construction projects.
BIM has attracted widespread popularity recently; however, there is several challenges concerning its definitions and expectations in early phases of construction projects. Evidently different organizations and people create their own definitions of BIM, based on the specific way they work with BIM. Thus, it is evident that there are differences in the way BIM is perceived by both different individuals and organizations within the construction industry.
As a result, it might be difficult to come up with a common definition of BIM for the entire construction industry. This can lead to misunderstandings concerning expectations from different stakeholders involved in construction projects where BIM is utilized. It is suggested that the definition of BIM should not be unilateral but rather encompass several key characteristics which have been attributed to it.

The fixed-width multiplier is attractive to many multimedia and digital signal processing systems which are desirable to maintain a fixed format and allow a little accuracy loss to output data.
This paper presents the Design of error compensated truncation circuit and its implementation in fixed width multiplier. To reduce the truncation error, we first slightly modify the partial product matrix of Booth multiplication and then derive an effective error compensation function that makes the error distribution be more symmetric to and centralized in the error equal to zero, leading the fixed-width modified Booth multiplier to very small mean and mean-square errors.
However, a huge truncation error will be introduced to this kind of fixed-width modified Booth multipliers. To overcome this problem, several error compensated truncation circuit approaches have been proposed to effectively reduce the truncation error of fixed-width modified Booth multipliers. Very Large Scale Integr. The operation of VSI is supported by a dc storage capacitor with proper dc voltage across it. Any change in the load affects the dc-link voltage directly.
The sudden removal of load would result in an increase in the dc-link voltage above the reference value, where as sudden increase in load would reduce the dc-link voltage below its reference value. Conventionally, a Proportional-Integral PI controller is used to maintain the dc-link voltage to the reference value.
It uses deviation of the capacitor voltage from its reference value as its input. However the transient response of the conventional PI dc-link controller is slow. To maintain the dc-link voltage at the reference value, the dc-link capacitor needs a certain amount of real power, which is proportional to the difference between the actual and reference voltages. To overcome the disadvantage of the conventional PI dc-link voltage controller, a fast-acting dc-link voltage controller is proposed.
To maintain the dc-link voltage of fast acting controller reference value is proportional to the difference between the squares of the actual and reference voltages.
Mathematical equations are given to compute the gains of the conventional controller based on fast-acting dc-link voltage controllers to achieve similar fast transient response. The value of the dc-link capacitor can be selected based on its ability to regulate the voltage under transient conditions.. The efficiency of the proposed controller over the conventional dc-link voltage controller has been developed in MATLAB environment, simulated and obtained related waveforms.

In image processing, various biometric applications, name identification from facial images plays an important role, Weber's Local Descriptor WLD will be used for face recognition for name identification. WLD is a texture descriptor that performs better than other similar descriptors but it is holistic due to its very construction.
We divide an image into a number of blocks, calculate WLD descriptor for each block and concatenate them. This spatial WLD descriptor has better discriminatory power. It is used to represent the image in terms of differential excitations and gradient orientation histogram for texture analysis. WLD is based on Weber's law and it is robust to illumination change, noise and other distortions. So it effectively analyzes the face features to accurate matching and name identification.
The feature extraction approach will be used for both test and database images to recognize for name identification. The face will be recognized by finding Euclidean distance between them. The proposed spatial WLD descriptor with simplest classifier gives much better accuracy with lesser algorithmic complexity than face recognition approaches.

Parallel and Distributed Systems, Vol. In this paper, a common fixed point theorem for six self mappings has been established using the concept of semicompatibility and weak compatibility in Fuzzy metric space, which generalizes the result of Singh B.

Zadeh, Fuzzy sets, Inform and Control, 8 , Steganographyis the art or technique of hiding messages in such a way that no one except the sender and the intended recipient suspects the existence of the message, a form of security through obscurity.
We use this concept wherein text is hidden behind the image and the intended recipient is able to view it. The purpose of the system is covert communication to hide a message from a third party. In this paper, a technique called digital signature is also included which is added to all the documents sent by the sender to increase the reliability and authenticity of the document.
Thus, the proposed system would help to hide the existence of confidential data and would increase the difficulty of detecting the hidden embedded data. We are also including facial recognition which automatically identifies the person by comparing selected facial features from the image and a facial database. Hence when an image is sent with data encrypted in it, the recipient's facial features will be compared with the one in the central database.
In this way the receiver is authenticated using facial recognition tool. Thus this paper gives a brief idea about image steganography that makes use of Least Significant Bit LSB algorithm for hiding the data into an image which is implemented through the Microsoft.
This system will prove to be helpful in areas where security of data is of utmost importance. It will also be very easy to share and send data to a recipient via a single image file. Reference  "Introduction to computer security" -Bishop, M. Subramanya and Byung K.

Acute hypotensive episode AHE is a serious clinical event, which can lead to irreversible organ damage and sometimes death. When detected in time, an appropriate intervention can significantly lower the risks for the patient.
The algorithm consists of probability distributions of MAP and information divergence methods for calculating the statistical distance between two probability distributions. The Bhattacharyya Distance is found out to be most accurate method for calculating such statistical distance. The comparison is also carried out for feasibility of Bhattacharyya distance with another divergence method like KL ivergence. Computers in Cardiology ; On information and sufficiency.

Princeton University Press, The ultraviolet UV region of electromagnetic radiation from sun occupies a section of wavelengths ranging from to 10 nm. It is highly ionizing and activates many chemical processes on different types of materials and living beings.
The amount of UV radiation at different places on the earth depends on the position of the sun during the day and the season of the year.
A decline in the amount of total ozone content TOC at a particular time also leads to an increase in UV radiation at that time.

Our goal is to detect when the distributor's sensitive data have been leaked by agents, and if possible to identify the agent that leaked the data.
In this project, we are giving the methodology for adding fake object into data. Fake object will be added through stegnography concept. Stegnnography is an ancient technique of data hiding or the stegnography is the art and science of hiding the existence of information, we contrast it with the related disciplines of cryptography And traffic security.
Many techniques are used to hide data in various formats in steganography. The most widely used mechanism on account of its simplicity is the use of the Least Significant Bit. Least Significant Bit or its variants are normally used to hide data in a digital image. This paper discusses technique to hide data in a colorful image using least significant bit.

An Analytical Approach Abstract: The pulse density modulation technique has been used in resonant power converters because its ability to maintains soft-switching for any level of output power. The sub harmonics of the switching frequency are in general undesired and are seen as a drawback. In this work are developed analytical equations to express the harmonics and sub harmonics components of a PDM signal.
It is still analyzed the PDM parameters variation and their effects in the frequency spectra.

These are suitable for memory applications due to their capability to correct large number of errors. For a sealant, I love jojoba oil. It would be nice to know how much each product cost. Pantene is the best product line for the best price. Thanks for this list! However just want to let you know I purchase my giovanni products from good ol' walmart!

Thanks so much, zainab1 AuNaturale I am going to try the water-based moisturizer and coconut oil sealant tomorrow after washing my hair after my workout. I have been natural sine like but need to take better care in the moisture department!! Does anyone still use Cholesterol??? If so does anyone do what Nikki says and add honey and oil?

Thank you so much for this site!!! I'm addicted to it! I've been transitioning for about a 1 year and a 5 months now and I couldn't figure out why my hair was so dry, but this site gave me all the tools I need to have healthy hair. I'm six months in as a long transitioner.
I purchased Yes to Cucumbers and love the way it makes my hair feel. I also love the smell. Thank you so much. I have 3 daughters and I am trying to make sure their hair is as healthy as possible and trying to stay away from sulfates and parabens and all the bad stuff!!! I just purchased pantene pro-v for relaxed and natural hair as well. Does anyone know anything about this product? I'm 6 months into my transition. I really needed to set a new regimen so I printed your post and took it with me shopping.
Thanks for taking the time to put this together. Just wanted you to know that your list is still helping people. I've been natural for years, at least 6, maybe even more.
I started with the big chop, and never regretted it. I wear my hair straight and in the summer I sport my natural curl.

I need a detangling conditioner that is hypoallergenic!
Nikki, I wanna know after you chop your hair what do you put on it. I have very little hair ,I wash it put some Shea butter on it. So can you help a sister. What does pommade do for styling the hair? Or rather, how do you use it? I'll also check youtube. This summer my roommate who has fine and straight hair was complaining about how dry and brittle her hair had become. I wanted to ask her "You flat iron multiple times a day and are recovering from your blonde phase, what did you expect?!
The next day she came to me as if I was a guru and said " I had been using Say Yes to Cucumbers conditioner until I noticed that it had Sodium Hydroxide in the ingredients list. I know that's lye and so I didn't want to keep using it; especially as a leave in. Even in small quantities, there's no good reason I can see for putting this on natural hair. Sorry guys, but I'm done with this one.
I just discovered the best shampoo for natural hair I've come across in ages. I tried it on a lark and OMG the softness I got was incredible. I only use it once a month to remove any buildup since I co wash weekly but I'm hooked on this. Perhaps you can find it in your local BSS and give it a try.
I'm pretty sure you'll add it to your list once you do! And many thanks for all the great tips - love your site! I have been transitioning for going on five months now and have definitely found your website helpful, especially since I'd almost given up.

I am a older women that want to know if henna will help my hair to grow like the younger women hair? Would like to try,but dont want to put money or time in the henna if their is something better. Going form perm to natural hair can somone help.
Best twist out of my life. Did it Wednesday night and its Sunday still going strong. I just pull my hair into a very loose ponytail at night and put my satin cap on top. You just have to add a light moisturizer every couple days to keep it shining! I have just been so lost! Please tell me what do you think about using a hair dryer to dry the hair especialy when using rods to set your natural hair.
I use a hair dryer minimal heat every week before twisting my hair. I use a little Jamaican Castor Oil when hair is dried, Results: Awesome when I twist out. So Nothing bad with hair dryer if you are taking good care of your hair.
My hair is very healthy.: I read your article in Essence about what to use in your hair to help fight "Humidity". You listed what to look for in the ingredients CN, thanks so much for the information.
Do you still use the same products in , or have you founds some new ones to add to the list. Again thanks for the information I would like to know have you changed anything products since CN, did you detangle your hair with a brush or comb when your first started using henna back in 07 or so. So far I like Shea Moisture. I have this list up on my phone whenever I go to pick up some new products! Have you tried Kinky Curly Knot Today? That's a great leave-in for twist outs!
