Analytical performance comparison of active and passive SMMW imaging for contraband detection

Significant efforts are underway to use either passive or active MMW and Sub-MMW imaging systems to detect objects concealed under clothing. Some have reached the point of commercial availability and have proved useful for contraband detection under controlled conditions. Studies have shown that when the conditions are uncontrolled, passive techniques become less desirable for contraband detection at standoff ranges which give the operators a margin of safety. In recent years, several programs have been funded to investigate using active techniques in the range of 100 to 1000 GHz for standoff detection out to ranges of 100m, a range which has been cited by some to be a desirable operating range. This paper will build on previous work to compare the performance of passive and active sub-MMW imagers used for detecting objects concealed under clothing. The analysis is designed to separate the effects of phenomenology and system components so that tradeoffs in transmitter and receiver characteristics can be performed. The derivation of the analysis and various examples of tradeoffs will be presented.

New Hybrid Desalination Design and Modeling

In order to adapt to the development of world integration, most modern ocean-going vessels are engaged in long transport routes voyages, so the demand for fresh water is very large. From the energy conservation, improving the amount of water production, saving shipping companies operating costs, increasing ship endurance capacity point of view, combine the vacuum system which has the feature of less salt content with the reverse osmosis water production system which has the advantage of large water production, now we design the new type composite desalination plant, and doing the model calculation, the study has a very high prospects for the development and practical application value.
Forecast Model of Phreatic Surface on Tailings Dam Based on GM-GRNN Theory

Due to the extremely complicated seepage boundary conditions of tailing dam, the calculation results adopting two-dimensional simplified theory may greatly different from the measured results. It is urgent need of an accurate calculation method to forecast phreatic surface. In-depth analysis of factors affecting tailings dam phreatic surface, phreatic surface prediction model based on GRNN and GM (1,1) was established. A tailing dam engineering is tested using this model. It shows that the model uses the advantages of "accumulative generation" of a Gray prediction method, which weakens the original sequence of random disturbance factors, and increases the regularity of data. It also makes full advantage of the GRNN approximation performance, which has a fast solving speed, describes the nonlinear relationship easily, and avoids the defects of Gray theory.
Effect of Driver Cell Phone Use on Queue Discharge Patterns at Signalized Intersections

Queue discharge patterns and driver cell phone use were monitored and analyzed at four intersections in Charlotte, North Carolina. Of the more than 3,700 drivers observed, about 13.3% were talking on a cell phone and approximately 1.8% were texting while driving. The saturation headways and start-up lost times of queues containing cell phone users were compared with queues lacking the presence of cell phone users. Results show that although text messaging has a clear negative effect on discharge patterns, talking on a cell phone has an insignificant effect. Secondary analyses imply that drivers talking on a cell phone have a stabilizing effect because they likely perform worse than attentive drivers but much better than those engaged in a visually demanding distraction. Findings also show that the performance of drivers talking on a cell phone is fairly consistent, whereas the performance of nonusers is inconsistent because of myriad other distractions with widely varying effects on driver abilities. The performance of texting drivers was found to be the most variable, perhaps because of the sporadic, often intense visual demands associated with texting while driving.
Global Management, Local Labour: Turkish Workers and Modern Industry

Recent years have seen considerable discussion about globalisation. Little of this has concerned one of the truly global forces - the management of multi-national and large domestic corporations - and the significance of modern management practices for workers in the developing world. This book examines the nature of work in the modern corporate sector in one particular developing country, Turkey. Based on extensive fieldwork in the white goods, car and textiles industries, it argues we are not witnessing in these sectors 'the industrial revolution over again' but the industrial revolution plus managers equipped with modern means of organisation and production. It examines the meaning of this for workers and questions some common assumptions about the meaning of factory work in modern western social science literature, especially in North America and Britain. Broadly conceived, the book offers much to those interested in ethnicity, gender and generational differences as well as in work, management, trade unionism, development and modernisation.
Some Measurement and Methodological Considerations in the Application of Subjective Workload Measurement Techniques

Previous research with the NASA Task Load Index (TLX) and the Subjective Workload Assessment Technique (SWAT) has demonstrated their sensitivity to variations in workload under flight and other complex work conditions but has not addressed some important measurement and methodological issues regarding their application. This article reviews data that address several such issues including the effects of delayed workload ratings, the effects of previous workload levels on ratings, and procedures used to combine subscale ratings into one overall estimate of subjective workload.
Physical characteristics of headphones used in psychophysical experiments

The IEC coupler, dummy-head and actual-ear responses, harmonic distortion, impulse response decay, phase rotation and group delay, external sound radiation, sound attenuation and acoustic crosstalk characteristics of six models of headphones, the TDH39, DT48, HD250 Linear II, HD414 Classic, HDA 200 and SR-Lambda Professional, are measured and compared. The results indicate that coupler responses and dummy-head responses are not identical to actual-ear responses in most models, open-air type headphones have poor sound shielding ability, and the harmonic distortion and phase characteristics of all headphones tested are not problematic.
POEs and Prototypes: Post–occupancy Evaluations Comparing Two Prototypical Flexible Group Work Spaces in the open office

This study uses post–occupancy evaluation as a method to examine two prototypical team work settings. The aim is to determine how these flexible team settings support group work processes and workers. The post–occupancy evaluation measures users’ behavior and reactions for both settings over the course of a year. The evaluation methodology is driven by a series of seven hypotheses related to how the physical setting may affect the interaction and effectiveness of groups. A multimethod approach involving written surveys, observations, and focus group interviews is used to gather and validate data for each hypothesis. The results indicate shared successes and problems with flexible components and setting design and also subtle differences due to variables in design and user groups. Overall the post–occupancy evaluation served to develop a broader understanding of how people interact with and in a flexible group work setting in the open office.
Full-wave analysis of a new microstrip-to-waveguide interconnect configuration

This paper presents a new interconnect configuration between microstripline and rectangular waveguide that yields a transition from one microstripline port to two waveguide ports. Most current transitions employ only one waveguide port. Electromagnetic coupling takes place through a slot in the narrow wall of the rectangular waveguide that coincides with a slot in the ground plane of the dielectric slab. Introduction of an E-plane waveguide fin yields additional control over the insertion loss level. The numerical method employed in the analysis, which makes use of Green's function expressions in a moment-method solution, is also described and numerical details are presented. Measured results verify the accuracy of the numerical model and illustrate that it is possible to obtain insertion loss levels of 0.25 dB with this configuration. Design data and a sensitivity analysis presented here further characterize the interconnect.
Microneedle array and insertion guide array for safe use of biomedical applications

A new method of using silicon microneedle array in Bio-Medical applications is introduced in this work. The hollow microneedle array with the facilitation of an insertion guide array have been designed and fabricated. The needles can be pushed down through the second layer of human skin with less-bending. The tip of microneedle will be led by the insertion guide to pierce the skin perpendicularly. The silicon bulk micromachining technique using an inductively coupled plasma (ICP) etcher has been employed to fabricate the microneedle array and the insertion guide array. The array chips are 5x5 mm2 for both structures. The needle array chip contains 100 microneedles with 100μm and 30 μm of the outer diameter and the hole diameter respectively. The guide array chip is 100 μm-thick and contains 100 guiding holes with 120 μm diameter. A buckling test of microneedle shows the result that there was no microneedle broken during the test via the guiding holes. Contrary, there were several microneedles broken during the penetration without the facilitation of the guide. The finite-element analysis also supports the test result. After the insertion with guiding has been tested and proved, a wet etching process was added in order to obtain sharper tips.
Productivity Change and Relative Efficiency of Korean Professional Baseball Teams

Most of professional baseball teams are not good for business condition because of operation costs in spite of support of mother company. This study measured the relative efficiency and productivity change of the Korean professional baseball teams using DEA model and Malmquist Index for 2006-2008. The main results of this study can be summarized as follows. First, in case of efficiency of CCR for 2006-2008, the number of efficient professional baseball teams(CCR value is one) are two(Doosan Bears, Samsung Lions), two(Doosan Bears, SK Wyberns), two(Lotte Giants, LG Twins) respectively.

Third, average of Malmquist Index representing productivity change for 2006-2008 are 1.0615, 1.0293 respectively. These values mean increase of productivity. Results of this study can be used by inefficient professional baseball teams to improve inefficiency.
Thermoelectrics Run Hot and Cold

Some materials exhibit thermoelectricity, a phenomenon not only useful for heating and cooling applications but also for power generation. In his Perspective, Tritt describes results reported by Sales et al. (p. 1325) on a class of thermoelectrics called skutterudites. These compounds are promising higher performance in applications such as deep space probes, new generation automobiles, and temperature stabilization.
Novel insights into the mechanisms by which lncRNA HOTAIR regulates migration and invasion in HeLa cells

ABSTRACT HOTAIR, as one of the few well-studied oncogenic lncRNAs, is involved in human tumorigenesis and is dys-regulated in most human cancers. The transcription co-activator factor YAP1 is broadly expressed in many tissues, and promotes cancer metastasis and progression. However, the precise biological roles of HOTAIR and YAP1 in cancer cells remain unclear. In this study, we showed that HOTAIR regulates H3K27 histone modification in the promoter of miR-200a to mediate miR-200a expression by recruiting EZH2. YAP1, as a potential target gene of miR-200a, aggravated the effects of miR-200a on the migration and invasion of HeLa cells. YAP1 activated the transcription of RPL23, which is a novel downstream transcriptional-regulator of YAP1. Agreement with this, the expression of YAP1 and RPL23 was dramatically decreased after injecting HeLa cells transfected with siHOTAIR in a xenograft mouse model. Accordingly, we propose a novel model of the molecular mechanism by which HOTAIR promotes the migration and invasion of cancer cells involving the miR-200a-3p/YAP1/RPL23 axis.
The empty running and return loading of road goods vehicles

The proportion of lorry-kilometres run empty in the UK declined by 11% between 1982 and 1993, yielding significant economic and environmental benefits. This paper examines possible reasons for this trend and identifies five contributory factors: the lengthening of lorry journeys, increasing number of drops per trip, expansion of load-matching services, growth in the reverse flow of packaging material/handling equipment and greater effort by shippers to obtain return loads. Original survey data are used to classify and rank the different types of return loading in which manufacturers and retailers engage. Company responses suggest that backloading is likely to increase significantly, though still be subject to numerous constraints. The paper examines these constraints in detail and suggests ways in which they might be relaxed. The development of supply chain management, advances in vehicle routeing software and increasing road transport costs are likely to promote more balanced vehicle loading.
Validate High Stakes Inferences by Designing Good Experiments, Not Audit Items: A Comment on “Self-Monitoring Assessments Educational Accountability Systems”

The use of large-scale assessments for making high stakes inferences about students and the schools in which they are situated is premised on the assumption that tests are sensitive to good instruction. An increase in the quality of classroom instruction should cause, on the average, an increase in test scores. In work with a number of colleagues over the past decade, Dan Koretz has argued that the validity of high stakes inferences from school-level improvements in test performance can be threatened by strategic instructional activities that serve to “inflate” test scores (Koretz & Béguin, 2010; Koretz & Hamilton, 2006; Koretz, McCaffrey, & Hamilton, 2001). This might lead people to erroneously conclude that students have learned and that the underlying tests serve as a good barometer for this when all that has been demonstrated is that the tests are sensitive to innovative methods of coaching. As a method of evaluating this phenomenon, Koretz and Béguin (2010) have proposed a system of “self-monitoring assessments” (SMA) in which “audit items” are incorporated into the operational design of existing tests. While I appreciate the underlying conceptual framework for score inflation being presented, I am pessimistic about the utility of the SMA approach. In this comment I lay out my objections and sketch out an alternative. In Figure 1, I present a simplified version of the framework Koretz and colleagues developed to characterize two ways that test scores can be actively inflated by the actions of schools and/or teachers. The circle in the diagram represents the target domain1 for inferences about student knowledge. The target domain is presumably populated with all the sorts of “things” that students would be expected to know about, say, mathematics by the end of grade 5. We assume that all this could be operationalized through the writing of content standards and the alignment of
MOSCAP's and MOSFET's on III-V Channel Materials with Si, Ge and SiGe Interface Passivation Layer

HfO2 and other high-k dielectrics have been considered as alternative to SiO2 in Si-based CMOS technology. The alternative dielectrics provide excellent opportunity for considering alternative channel materials such as GaAs. Our results showed that in order to achieve unpinned Fermi level, a thin Si or Ge interface passivation layer (IPL) in between GaAs and HfO2 is effective [1-2]. Si IPL MOSCAPs have been shown to exhibit less C-V hysteresis, while Ge IPL devices can provide very thin EOT [2]. In this talk, we will present the electrical and materials characteristics of TaN/HfO2/GaAs MOS capacitors and MOSFETs with Si or Ge IPL. In addition, SiGe IPL under various deposition time and post deposition anneal (PDA) conditions has also been investigated. Using different Si and Ge deposition rate, we adjust the Si:Ge ratio in the SiGe IPL. Thin EOT (~1nm) in Ge-rich IPL, low frequency dispersion (<5%), low hysteresis and low leakage current density in Si-rich IPL have been obtained. We will also discuss other alternative channel materials such as InGaAs.
Supply chain immunity: a methodology for risk management

Supply chain risk management is an important area that has both tremendous practical significance and research potential. Risks can range from very frequent low impact variations to disruptive effects. Biological systems are also similarly under constant attacks and their immune systems have evolved to protect them very effectively. Building on this immune system metaphor, this paper describes a methodology for supply chain risk management in manufacturing and services. The methodology leverages the supply-chain operations reference (SCOR) sub-processes to create distributed solutions for supply chain risks. Two key features that cater to the needs of current supply chain risk management are the ability to uncover the impact of the risk over the entire supply chain and rapid reconfiguration of the supply chain.
Políticas de controle do câncer de mama no Brasil

Este artigo tem como objetivo central examinar a trajetória histórica das políticas de controle do câncer de mama feminino no Brasil em diferentes momentos históricos. As primeiras intervenções públicas nessa direção no país surgiram em meados do século XX e visavam ao desenvolvimento do cuidado oncológico de maneira individual. A intensificação das medidas estratégicas para o seu controle ocorreu somente a partir dos anos 2000, com perceptível desenvolvimento de ações coletivas e incentivo à prevenção, de maneira a incidir diretamente no controle da doença. O estudo contou com pesquisa bibliográfica sobre a temática, associada à análise dos documentos oficiais, como: normativas, portarias e legislações nacionais. Os resultados demonstram avanços na estruturação do cuidado da doença, sobretudo pela implantação de políticas, programas e sistemas específicos. Tais avanços estratégicos contribuem positivamente para o controle de riscos e agravos da doença. Mas, apesar desses avanços, a realidade observada ainda permanece em certo descompasso, perceptível pelo elevado e crescente índice de mortalidade.
Walking mode classification from myoelectric and inertial fusion

Transtibial amputees are generally restricted to the use of non responsive prosthetic systems which have been shown to require increased metabolic energy during normal gait [1] and can contribute to pain in the residual limb [2] among other unfavorable outcomes. Development of responsive lower limb prostheses is restricted due to the function of the human ankle which changes based on speed and type of locomotion. The ideal prosthetic would detect the patient’s motion intent to match both intensity and type of locomotion task. Implementation of motor intent detection should help restore normal limb function. Recent advances have shown the benefit of myoelectric and mechanical sensor fusion towards motion intent classifications. For upper limb amputees, a single accelerometer has shown benefit in classifying different types of hand grasps [3]. For transfemoral amputees a 6 axis pylon-implanted load cell has allowed increased walking mode classification accuracy [4]. It is believed that the continued exploration of EMG and mechanical fusion strategies will advance myoelectric control towards the development of commercially available systems for lower limb amputees. The purpose of the current study was to evaluate the potential for walking mode classification from both electromyography (EMG) signals and inertial measurements units (IMUs). © 2012 ASME
ANALISIS KINERJA TEKNIK SPACE-TIME BLOCK CODEDPADA SISTEM KOMUNIKASI KOPERATIF

Sistem komunikasi koperatif merupakan perluasan dari transmit diversity, sistem MIMO dan jaringan ad-hoc. Konsep jaringan ad-hoc digunakan pada sistem komunikasi koperatif, yaitu adanya beberapa Mobile Station (MS) yang saling berkomunikasi dan mengirimkan datanya ke MS lainnya dengan maksud menyebarkan sinyal yang berlebihan dan secara bersamaan mengirimkan data ke Base Station (BS) untuk mendapatkan transmit diversity tanpa menggunakan antena jamak. Pada tugas akhir ini telah dibahas mengenai sistem komunikasi koperatif yang menggunakan konfigurasi multiple-access channel with relaying, dimana pada konfigurasi ini, user bertindak sebagai source maupun relay secara bergantian dan menggunakan metode decode-and forward sebagai strategi untuk pemrosesan sinyal di relay (user lainnya) dan proses combining di BS. Sedangkan metode STBC digunakan sebagai pengkodean pada kedua user. Dari hasil simulasi diketahui bahwa kinerja STBC-koperatif pada kanal yang dipengaruhi AWGN dan rayleigh flat fading bergantung pada kondisi kanal uplink karena adanya diversity pada kanal uplink yang didapatkan dari kerjasama user dalam pengiriman data ke BS, sehingga STBC-koperatif akan menghasilkan BER sebesar 10-4 bila Eb/No kanal antar user bernilai minimum 30 dB dan Eb/No kanal uplink bernilai minimum 24 dB. STBC-koperatif dengan Eb/No kanal antar user 30 dB memiliki kinerja lebih baik 4 dB dibandingkan MRRC non-koperatif karena adanya perbaikan kinerja yang didapatkan dari kerjasama antar user serta memiliki kinerja mendekati STBC nonkoperatif tetapi hanya lebih buruk 2 dB karena adanya penambahan derau AWGN pada proses pertukaran data di kanal antar user.
