An experimental investigation of the influence of the moving people on the indoor radio propagation

Using a new scenario for measurements, the influence of the human traffic on the indoor radio propagation is investigated. This new scenario permits one to obtain a signature of moving people all day long (and their influence on the power loss and RMS delay spread). In order to obtain better results for the radio coverage, a new random term must complete the results obtained for power-distance relationship in the absence of moving people.
Writer identification using Gabor wavelet

This paper focuses on a system to fulfill writer identification, which identifies a person with his/her handwriting. A text independent method is proposed in this paper, which involves no local feature analysis. First, a preprocessing method is employed to normalize script images. Then, 2D Gabor wavelet technique is developed to extract the global features. Finally a K-nearest neighbor (K-NN) classifier is designed to identify the person with the identified handwriting. Illustrative experiments are made with 110 specimens of 50 people, and a result of 97.6% accuracy is achieved with the writer identification approach proposed in this paper.
ACCURATE SLIDE POSITIONING USING FAST ADAPTIVE-TEMPLATE MATCHING IN AN AUTOMATED MICROSCOPE

In an automated microscope, the stage presents the slide to the optical path in the desired position. This article presents an accurate slide positioning algorithm which finds the relative offset from the zero of off-line calibration when the standard slide with a ring fiduciary mark is loaded on the stage. The relative offset is the difference between the zero by the offset calibration tool and the real-time zero position of the ring mark computed by the scheme. The slide positioning algorithm utilizes the adaptive-template matching method to detect the ring mark precisely, in which a fast sum of absolute differences is employed to reduce the computational complexity of template matching. Computer simulations with real clinical slides containing epithelial debris and nuclei show that the proposed algorithm yields an accurate performance in terms of detecting the ring mark and estimating the relative offset with a great reduction in computational complexity.
Postural control strategies during quiet standing in normal children

The purpose of this study is to determine the significance of hip rotation strategy during quiet standing in normal children. We have developed linear expressions among the coordinates of right and left center of pressure data to identify and separate hip abduction/adduction, hip rotation, ankle inversion/eversion, and ankle plantar/dorsiflexion strategies.
Social networking: a collaborative open educational resource

Studies undertaken since the introduction of Web 2.0 have focussed mainly on open educational resources (OERs) such as email, blogging and virtual learning environments. No consistent efforts have been undertaken to study the use of social networking sites as a tool for learning in the second language classroom. This study examined the use of social networking sites as a means of establishing an asynchronous online environment for use in language learning in a classroom setting. The findings described are based on the use of a social networking site called Ning in a classroom during a summer school project, which was conducted at a further education college in the UK. The project focussed in particular on informal language practice when using social networking sites. The paper then examines the effect the use of the social networking tool had on group cohesion and learner-to-learner interaction, and how these, in turn, enhanced informal language learning due to an increase in learner collaboration. The study found that the use of Ning enhanced group cohesion and that learners started working in different groups once Ning was introduced. Finally, it highlights the potential technical and administrative barriers that can impede an institution in implementing its educational strategy in regards to OERs – in this case, social networking sites in the classroom. The further education college in which this study took place had no policies in place in regards to the use of OERs in the classroom, thus the paper concludes with recommendations in regards to training and policies so that researchers and practitioners can learn from the project.
Faults and fault effects in NMOS circuits - impact on design for testability

VLSI circuits currently being designed are so complex that it is now extremely difficult to test them adequately to determine whether or not they have been processed correctly. Design for testability (DFT) techniques are often used in an attempt to ease this problem by identifying and redesigning potentially ‘difficult-to-test’ parts of the circuits. The ‘testability’ of the circuit is usually evaluated in terms of the stuck-at fault model. However, there have been growing doubts over the ability of this model to cover certain common faults that can occur in MOS processing (at present, the dominant VLSI technology). The paper describes software simulations of faults in simple NMOS logic circuits showing that not all fault effects in NMOS circuits are modellable as ‘stuck’ nodes. An improved fault model which would better reflect MOS fault effects has yet to be defined. Until such an improved model is available, DFT rules for MOS circuits are best regarded as provisional. We therefore conclude with a discussion of ad hoc ‘physical design for testability’ techniques that exploit current understanding of the relation between MOS faults and their fault effects.
Keynote lecture research challenges and proposed solutions to improve availability and quality-of-service in future IPTV systems

During the last decade the offering of TV programs via the Internet by means of an IPTV service using multicast communication has become more and more common. Currently, the largest number of IPTV subscribers is located in Western Europe and in the Asia Pacific region. In particular, France is still the leading country for IPTV and about 17 % of the French population is presently already using an IPTV service. A typical way to offer IPTV to customers (by Telcos and Internet Service Providers) is to offer this service via DSL. However, also wireless access networks such as Wi-MAX or LTE become increasingly relevant. The transmission of TV programs leads to very large bandwidth requirements within the communication infrastructure if a large number of TV channels (> 100) has to be offered in parallel and possibly also in high quality (e.g., HDTV quality). Therefore, serious bottlenecks in the communication network may occur which may lead to a temporary unavailability of some of the more unpopular TV channels. The talk summarizes the comprehensive experiences in IPTV research (both for DSL and WiMAX access) within the Telecommunications and Computer Networks Division at University of Hamburg. In particular, emphasis will be given to our recent research results related to new measures (called “multicast gain”), which allow one to quantitatively assess the usage of multicast versus unicast, both, for wired and for wireless links in networks; realistic models to characterize the behaviour of IPTV users; methods to calculate the overhead resulting from multicasting and unicasting TV channels in WiMAX based IPTV systems; a new access control algorithm for TV channels offered via DSL which favours more popular channels as compared to infrequently watched ones and turns out to increase channel availability quite strongly in numerous high-load situations; algorithms to reduce either the channel switching delay or the channel unavailability in IPTV systems with users zapping channels frequently. The research results presented should be a valuable source of information mainly for Internet Service Providers (ISPs) or Telcos offering IPTV services, but also to re-searchers, developers, (post-) graduate students, etc who are interested in the analysis, assessment, tuning, construction and/or installation of efficient and highly available IPTV systems with DSL- or WiMAX-based access networks.
Fast classification and segmentation of high-resolution images of multiple and complicated colonies

This paper presents a methodology for high resolution image classification and segmentation. The size and information volume of the images, taken by a high resolution digital camera, will be tens to hundreds times as the ones taken by an ordinary CCD camera. In order to speed up the image segmentation process of the large images, we classify the images first by using a low resolution image, then, segment them by a fast segmentation algorithm. The algorithm is studied mainly based on multi-resolution technique and the fusion of edge detection result and similarity segmentation result. By use this methodology, the whole image segmentation process time is reduced by tens' times than traditional segmentation methods. And the accuracy of the image segmentation is not decreased.
Batch processing algorithms for blind equalization using higher-order statistics

Statistical signal processing has been one of the key technologies in the development of wireless communication systems, especially for broadband multiuser communication systems which severely suffer from intersymbol interference (ISI) and multiple access interference (MAI). This article reviews batch processing algorithms for blind equalization using higher-order statistics for mitigation of the ISI induced by single-input, single-output channels as well as of both the ISI and MAI induced by multiple-input, multiple-output channels. In particular, this article reviews the typical inverse filter criteria (IFC) based algorithm, super-exponential algorithm, and constant modulus algorithm along with their relations, performance, and improvements. Several advanced applications of these algorithms are illustrated, including blind channel estimation, simultaneous estimation of multiple time delays, signal-to-noise ratio (SNR) boost by blind maximum ratio combining, blind beamforming for source separation in multipath, and multiuser detection for direct sequence/code division multiple access (DS/CDMA) systems in multipath.
A* Algorithm Based Optimization for Cloud Storage

Cloud Storage provide users with storage space and make user friendly and timely acquire data, which is foundation of all kinds of cloud applications. However, there is lack of deep studies on how to optimize cloud storage aiming at improvement of data access performance. In this paper, mathematical description for cloud storage optimization is given and as a objective optimization problems which is solved by our proposed optimized A* algorithm, as a result the data is distributed in appropriate nodes with the best efficiency. The experimental results demonstrate the performance of the algorithms is feasible in reducing MakeSpan, and the optimization can produce a storage strategy which is keeping with the real conditions. Besides, lastly, the time limitation of A* algorithm is investigated in experiments.
CONCURRENT ENGINEERING : Research and Applications An Agent-based Architecture for Concurrent Engineering

This paper describes a reference architecture for a concurrent engineering environment. The architecture embeds applications in wrappers to treat the applications as individual reasoning agents. Embedded applications have included planning, vision, simulation, and robotic control modules. These agents negotiate from various perspectives to arrive at globally acceptable solutions. The agents transmit information and negotiate using a canonical vocabulary based upon an international standard for data exchange. Because our implementation of the architecture explicitly considers real-world issues, such as heterogeneous systems, distributed processing, faults, meeting real-time deadlines, and communication delays, the implementation of architecture facilitates rapid transferral from laboratory experiments to field systems.
High-Performance Acellular Tissue Scaffold Combined with Hydrogel Polymers for Regenerative Medicine.

Decellularization of tissues provides extracellular matrix (ECM) scaffolds for regeneration therapy and an experimental model to understand ECM and cellular interactions. However, decellularization often causes microstructure disintegration and reduction of physical strength, which greatly limits the use of this technique in soft organs or in applications that require maintenance of physical strength. Here, we present a new tissue decellularization procedure, namely CASPER (Clinically and Experimentally Applicable Acellular Tissue Scaffold Production for Tissue Engineering and Regenerative Medicine), which includes infusion and hydrogel polymerization steps prior to robust chemical decellularization treatments. Polymerized hydrogels serve to prevent excessive damage to the ECM while maintaining the sophisticated structures and biological activities of ECM components in various organs, including soft tissues such as brains and embryos. CASPERized tissues were successfully recellularized to stimulate a tissue-regeneration-like process after implantation without signs of pathological inflammation or fibrosis in vivo, suggesting that CASPERized tissues can be used for monitoring cell-ECM interactions and for surrogate organ transplantation.
Web Spoofing: An Internet Con Game

Web spoofing allows an attacker to create a “shadow copy” of the entire World Wide Web. Accesses to the shadow Web are funneled through the attacker’s machine, allowing the attacker to monitor all of the victim’s activities including any passwords or account numbers the victim enters. The attacker can also cause false or misleading data to be sent to Web servers in the victim’s name, or to the victim in the name of any Web server. In short, the attacker observes and controls everything the victim does on the Web.
Feedback Analysis of Transcutaneous Energy Transmission with a Variable Load Parameter

The transcutaneous energy transmission system (TETS) composed of a Class‐E amplifier may operate at a state away from the optimum power transmission due to the load variation. By introducing the feedback‐loop technique, the TETS can keep the optimum state with constant output voltage by adjusting the important design parameters, that is, the duty ratio and frequency of the driving signal and the supply voltage. The relations between these adjusted parameters and the load are investigated. The effectiveness of the feedback technique is validated through a design example with a variable load parameter. The experimental results show that the Class‐E amplifier in the feedback loop can keep operating at the optimum state under the condition of up to 50 percent variation of the load value.
Training humanitarian professionals at a distance: testing the feasibility of distance learning with humanitarian professionals

Training is an essential part of the professional development of staff working for international humanitarian organizations. While humanitarian workers are being deployed around the world to provide life‐saving relief assistance in often‐hazardous missions, it is imperative for organizations to ensure that staff members understand the mission and protocol of their organizations and that they develop an appreciation for the impact their work has on beneficiaries. Demand for such training has been expanding exponentially over the last decade with the growing number of humanitarian organizations and personnel. In the United Nations alone, an estimated 37,000 civilian personnel are being employed as part of UN humanitarian operations, an increase of 54% since 1997; 75% of this personnel is composed of national staff of the countries of operation (United Nations, 2008). With the increasing reliance of humanitarian organizations on national staff to manage their field operations, the professional development of staff members poses an ever‐growing challenge due to the remoteness and distribution of staff, limiting organizations’ ability to maintain the coherence and cogency of their mission and methods. Although many international humanitarian organizations have adopted some form of distance learning into their staff training, few organizations have evaluated the effectiveness of their distance learning programs. This research briefly evaluates the literature relevant to the use of distance learning for training professional staff in the humanitarian field, assesses how distance learning programs are being used among select humanitarian organizations based in the USA, and reviews the results of a pilot distance learning course offered to mid‐career professionals working on international humanitarian issues in a professional capacity.
Hyperthermia and Plasma Membrane Ca ATPase: Is There Any Effect of HT on PMCA?

Giris ve Amac:Hipertermi (HT) ile kanser hucrelerini tedavi etme fikri en az 5000 yil oncesine dayanir. Kanser arastirmalarindaki gecmis teknolojiler, ozellikle derin cekirdekli tumorlerde, tam olarak etkili ve homojen bir isitma saglayamadigindan dolayi modern kanser arastirmalarinda HT’ye ilgi eksikligine sebep oldu. Ayrica, HT'nin kanser hucrelerinde apoptozu indukledigi bilinmektedir. Ote yandan, plazma membrani Ca ATPaz (PMCA), apoptoz yolaklarinda onemli bir pompadir. PMCA, hucredeki Ca iyonlarini hucrenin disina pompalar. Bu calismanin amaci HT'nin PMCA kinetik parametrelerine etkisini degerlendirmektir. Yontem:PMCA uzerinde HT'nin etkisini degerlendirmek icin, kirmizi kan hucrelerinin plazma membrani kullandik. Saglikli donorden izole edilen insan kirmizi kan hucreleri, termomikser kullanilarak 30 dakika, 60 dakika, 90 dakika, 120 dakika boyunca 37oC, 44oC, 50oC'de isitildi. Eritrositler (39ul) lizis cozeltisi 1,7ml eklendi ve 15 dakika inkube edildi. Inkubasyon sirasinda karisim hafifce karistirildi. Karisim 0°C'de 20 dakika icin 17000 xg'de santrifuje tabi tutuldu. Bunlar, 1,7 ml KCl tampon icinde yeniden suspansiyona alinmis ve tekrar santrifuje tabi tutulmustur. Daha sonra, eritrositlerden hemoglobin cikarilir. Bundan sonra, 0.4 ml'lik bu bos eritrosit suspansiyonu, Indo 1FF-AM ile 0.1 ml tampon ile karistirildi. Bu suspansiyon, buz uzerinde 15 dakika inkube edildi. Bu bos eritrositler 37°C'de 45 dakika inkube edilerek tekrar kapatilmis ve kullanima kadar buz uzerinde depolanmistir. Sonuclar:Kalsiyum konsantrasyon seviyelerine gore kontrol ile diger sicaklik arasinda belirgin farklar vardir. Ayrica, 37oC ile diger sicaklik arasinda belirgin bir fark vardir. PMCA 37oC uzerindeki sicakliklarda cok iyi calismadi. Bu nedenle, yuksek kalsiyum konsantrasyonu olculdu. Pompa duzgun bir sekilde calisiyorsa, kalsiyum konsantrasyon seviyesi zamanla azalacaktir. Aksine, eritrosit keseciklerinde artan kalsiyum konsantrasyon seviyeleri olctuk. HT’ye maruz kalan PMCA, yuksek sicakliktan etkilenir ve PMCA calismaz, boylece Ca iyonlari hucrelerden disari cikamaz. Hucre olumu isinin etkisi ile bozulan PMCA kinetiginden dolayi tetiklenmektedir.
Music from Motion: Sound Level Envelopes of Tones Expressing Human Locomotion

The common association of music with motion was investigated in a direct way. Could the original motion quality of different gaits be transferred to music and be perceived by a listener? Measurements of the ground reaction force by the foot during different gaits were transferred to sound by using the vertical force curve as sound level envelopes for tones played at different tempi. Three listening experiments assessed the motion quality of the resulting stimuli. In the first experiment, where the listeners were asked to freely describe the tones, 25% of answers were direct references to motion; such answers were more frequent at faster tempi. In the second experiment, where the listeners were asked to describe the motion quality, about half of the answers directly related to motion could be classified as belonging to one of the categories of dancing, jumping, running, walking, or stumbling. Most gait patterns were clearly classified as belonging to one of these categories, independent of presentation tempo. In the third experiment, the listeners were asked to rate the stimuli on 24 adjective scales. A factor analysis yielded four factors that could be interpreted as Swift vs. Solemn (factor 1), Graceful vs. Stamping (factor 2), Limping vs. Forceful (factor 3), and Springy (factor 4, no contrasting adjective). The results from the three experiments were consistent and indicated that each tone (corresponding to a particular gait) could clearly be categorised in terms of motion.
Mind and the World

In the introduction Sir Russell Brain states as the thesis of this book " that it is possible to accept all the new knowledge which neurophysiology and psychology can provide and yet preserve the mind's autonomy in its own sphere. " That is a very arresting statement to make at a time when we are assailed by so many assertions to the contrary, assertions which are also claimed to be based on the "new knowledge. " Sir Russell Brain's philosophical position of dualism is virtually indistinguishable from that of Sherrington and is likewise based on a very clear understanding of the role of neurophysiological events in perception. An attractive feature of the book is the effective use that is made of concrete illustrations in the argument, which is thus given a lucidity that is as unusual as it is welcome in this perplexing field. Chapters 4, 5, and 6 make particularly good reading, and, in his deft handling of the concepts of " perceptual world " and " physical world," Sir Russell Brain has made an important contribution that should clear up many old controversies and confusions in the field of perception. To some extent Chapter 1 is also on the same theme, but was written several years earlier, and is much less satisfactory. The criticism of physiological idealism is not convincing and in fact is largely answered in Chapters 5 and 6, where it is shown that physiological idealism can be developed so that such a process as projection becomes intelligible. Comparison of the first with these later chapters gives a measure of the progress that Sir Russell Brain has made, and gives hope that we may expect further valuable contributions from him. In particular one hopes that his success with perception will tempt him into the field of will, the "I-doing " of Sherrington. The last chapter, on the " Status of Mind," is in the form of a dialogue between author and reader, and gives the author a chance to develop some new arguments and in particular to attack the views that Professor G. Ryle develops in his book The Concept of Mind. Again one is impressed by the effectiveness with which some philosophical arguments are demolished by reference to the neurophysiological processes concerned in perception. In conclusion, this book is strongly recommended to all who take an intelligent interest in the problems of the nature of man and his relationship to the world. It can be read by those who have no technical knowledge of neurology. J. C. ECCLES.
