are the main source of increased IL-7 expression in primary SS, which would require analysis of a larger sample of patients with primary SS in order to demonstrate whether expression of IL-7 is increased primarily in the SGs of patients, since the study by Bikker et al included only 15 patients (3). Otherwise, the results of studies using SGECs to investigate the role of IL-7 in primary SS pathophysiology may be of no value and may even be misleading for understanding the association between IL-7 and primary SS.

A new approach for measurement of the torque-speed characteristics of induction motors

The authors present a new measurement technique for the determination of the torque-speed characteristics of induction motors. This technique is in compliance with the IEEE standard test procedure for polyphase induction motors and generators. The basic principle of this new approach consists of three main steps. The first is dynamic measurement of the speed as a function of time. The second is digital filtering of the raw speed data. Finally, the speed signal is numerically differentiated to obtain the acceleration from which the torque of the machine can be found. Experimental tests using two 20 HP induction motors confirmed that this approach is more advantageous than other methods. Also, the method produces accurate results over the full speed range of the machine in contrast to some other methods.
Réalisation et expérimentation d'un cuiseur solaire boîte à surface réceptrice inclinée muni d'un réflecteur plan

After simulation of incident solar radiation distribution on the plate absorber of a box solar cooker with inclined aperture area, during the year in arid regions, in this paper; an attempt has been made to realize the first box solar cooker in Applied Research Unit on Renewable Energies; which is equipped with a reflector (booster mirror) for maximum energy collection. Mechanical design and optical simulation of the cooker during the test month are necessary.

The results obtained for these first tests are satisfactory and very
Global Distribution of Concurrent EMIC Waves and Magnetosonic Waves: A Survey of Van Allen Probes Observations

Recent studies have reported the simultaneous observation of Magnetosonic (MS) waves and Electromagnetic ion cyclotron (EMIC) waves. In this study, a detailed survey of the concurrent EMIC waves and MS waves is performed using the Van Allen Probes observations from 2012 to 2017. The results suggest that most of the concurrent EMIC waves and MS waves are H+ band EMIC waves and MS waves. The favorable geomagnetic conditions for the concurrent EMIC waves and MS waves are AE* ≥ 500 nT inside the plasmapause and AE* ≥ 100 nT outside the plasmapause. Although EMIC waves are generally stronger than MS waves, stronger MS waves than EMIC waves are more likely to occur during moderate and active geomagnetic times. Our study is consistent with the most recent research, and provides more detailed information that helps us to deepen our understanding of the concurrent EMIC waves and MS waves.
Selecting Quality-standard and Resource-allocation Proposal under Constrainedly Periodical Budget for Projects in New Product Development

This paper aims to propose an approach to select quality-standard and resource-allocation proposal for projects in new product development. We consider each R&D category involves redesigning or upgrading a specific current product. This work propose an approach to treat the multi-standard and multi-allocation project selection problem in which the scheduling is also considered concurrently under constrained periodically budget. The proposed approach consists of following four components: (1) selecting a project advancement strategy to serve as a scheduling framework for taking into account soft factors in scheduling process, (2) employing the expected brand-image scores of consumers as the objective function for ultimately increasing average profitability, (3) providing a model in which the selection of quality-standard proposal of a project, as well as the multi-project scheduling are involved, and (4) transforming the objective function into an appropriate form in which the parameters can be estimated more easily and the objective value has a clear managerial implication.
Introduction

Tanzania is one of the most important countries in Africa for biodiversity conservation. Harboring a significant proportion of the Eastern Afromontane global biodiversity hotspot (Kilimanjaro, the Eastern Arc Mountains, the Southern Tanzanian Highlands, and the eastern Albertine Rift mountains), it also borders Lake Tanganyika, the world’s second-deepest lake, and the marine islands of Pemba, Zanzibar, and the Mafia Archipelago (Mittermeier et al. 2004). Tanzania is, however, perhaps best known for its terrestrial megafauna with protected areas including Serengeti National Park, Ngorongoro Conservation Area, and Selous Game Reserve. The 25,000-km2 Serengeti-Mara Ecosystem, recognized as a World Heritage Site and more recently as a Global Wilderness Area (Mittermeier et al. 2002), is the world’s last intact migratory ecosystem and home to more than 2 million ungulates and perhaps the largest and the most diverse guild of carnivores in Africa (Sinclair et al. 2007b [this issue]). Tanzania also has one of Africa’s most extensive networks of protected areas: 25% of the country’s 1 million km2 is managed for conservation in national parks, game reserves, game-controlled areas, and forest reserves. This remarkable achievement has been attained despite Tanzania being one of the world’s poorest countries, with an average per capita income of only $US300 per annum. The conservation of Tanzania’s natural resources was made a national priority in a presidential declaration by Julius Nyerere in 1961 in what is known as the Arusha Manifesto. With this high degree of political support, the protection of Tanzania’s wilderness areas became government policy. Tanzania continues to show a strong commitment to conservation and in recent decades has reaped significant economic benefits through wildlife tourism and sport hunting (Thirgood et al. 2007). The long tradition of conservation management in Tanzania is matched by a long history of wildlife research. Initially, ecological surveys in the 1950s were encouraged by the British authorities to help define the boundaries of the protected areas (Pearsall 1957; Grzimek & Grzimek 1960). This effort expanded greatly in the 1960s, particularly with establishment of the Serengeti Research Institute, where a wide-ranging program of ecological

High Frequency GaN Drain Supply Modulators for Radio-Frequency Power Amplifiers

Supply modulation, or envelope tracking (ET), is a system efficiency improvement technique in radio-frequency (RF) transmitters where a power converter operating as drain supply modulator (DSM) provides an RF power amplifier (RFPA) with time-varying envelope waveforms. DSMs need to have high bandwidth, low tracking error and high efficiency. This thesis focuses on the design of the DSM using GaN-on-SiC technology for a 20 V ET system with X-band RF transmitter. The signals considered are 20 MHz OFDM and 20 MHz QPSK with 10 W peak output power. The topology chosen is a multi-phase pulse-width modulated (PWM) buck converter. Zero-voltage switching (ZVS) technique is used for high efficiency operation at high switching frequencies. A fourth order output filter design method that supports ZVS operation is proposed to accommodate both high bandwidth and high efficiency. Monolithic gate driver and half-bridge power-stage integration is a key step in addressing challenges in 50-100 MHz buck converter design. An analytical loss model is developed and used to optimize the monolithic GaN chips, which are then used to construct high-efficiency, wide-bandwidth synchronous buck converter prototypes implemented as DSMs. The converter prototypes are tested at various duty cycles and output power levels. The loss model and the design optimization results are verified by experimental results. The tradeoffs in multi-phase converter design is also discussed based on a total efficiency optimization method. Several multi-phase converter prototypes are tested, analyzed and compared. The resulting design shows record 97% efficiency at 10 MHz and 91% efficiency at 100~MHz. Accurate tracking of a 20 MHz LTE (100RB) envelope signal is demonstrated with 89.7% power stage efficiency and 83.3% total efficiency. Successful operation of the complete ET transmitter system is demonstrated.
Train Timetable Rescheduling Generation Based On Vehicle Type And Train Route Combinations

Train rescheduling means a transient situation to correct a train diagram in a suspended state due to traffic accidents or disasters. automatic (or half manual) rescheduling has been studied, and such previous research has shown promising results. In this paper, we describe a train timetable rescheduling method. In Japanese urban areas, some private companies operate on each other’s tracks. If vehicle types have limitations due to ground facilities or company rules, the vehicle has to be operated under these limitations even when running on a rescheduled timetable. even if the ground facilities of different companies have uniform conditions, local and rapid trains must be operated in a distinct manner. Therefore, we suggest a rescheduling method. With this method, each vehicle type and its vehicle routes based on the track layout are registered, and rescheduling diagrams are composed with the route combinations. Important conditions to decide the combinations are vehicle location at the operation resumption time and the introduction of same-type vehicles at an originally unscheduled timing. We compare the traffic effects for some combinations of the latter situation where originally unscheduled same-type vehicles are introduced for rescheduling. The evaluation values are average headway time and its standard deviation at all stations on the timetable. We apply our rescheduling method to a theoretical line and timetable modelled on existing urban lines in Japan where trains go and come back on double tracks, and indicate the efficacy of our resched-uling method.
Rural Electrification Program in Indonesia: Comparing SEHEN and SHS

In 2014, the Indonesian government had targets to obtain 80% of electrification ratio and 98.9% of rural electrification ratio. Extending the grid and off-grid connection has been done to obtain the targets. This paper aims to compare two main programs on rural electrification namely Super Extra Energy Saving (Super Ekstra Hemat Energi, SEHEN) that belongs to the PLN (state-owned company in electricity) and the Solar Home System (SHS) that is financed by the Ministry of Energy and Mineral Resources (MEMR). Indonesia started the rural electrification program in the late 1950s, but how to provide electricity in a sustainable ways both organizationally and institutionally still becomes a big challenge. The experiences from East Nusa Tenggara provinces showed that both SEHEN and SHS can instantly improve electrification ratio, but government needs to synchronize the technical, administrative, and financial aspect from the two programs. Without any improvements in designing the program, we argue that the existing program is not sustainable.

In this paper, we have summarized various routing protocols in wireless sensor network like TEEN, APTEEN etc.
Microstructural and geochemical studies of Higher Himalayan Leucogranite: implications for geodynamic evolution of Tertiary Leucogranite in the Eastern Himalaya

The Higher Himalayan Leucogranites (HHLG) intruded into the high grade rocks of the Higher Himalayan Crystallines (HHC) in Arunachal Himalaya of the Eastern Himalaya, yield distinctive field data, petrography, microstructures, geochemical and mineral chemistry data. The Arunachal HHLG are characterized by the presence of two micas; normative corundum; high contents of SiO2 (67–78 wt.%), Al2O3 (13–18 wt.%), A/CNK (0.98–1.44) and Rb (154–412 ppm); low contents of CaO (0.33–1.91 wt.%) and Sr (19–171 ppm), and a high ratio of FeO(tot)/MgO in biotite (2.54–4.82). These distinctive features, along with their strong depletion in high field strength elements (HFSE), suggest their affinity to peraluminous S‐type granite generated by the partial melting of crustal material. Geothermobarometric estimations and mineral assemblages of the HHC metapelites confirm that the HHLG were probably generated in the middle crust (~20 km) and the produced melts intruded the HHC in the form of sills/dykes. Microstructurally, the HHLG shows high temperature deformation features including chessboard extinction in quartz and cuspate/lobate grain boundaries between quartz and feldspars (plagioclase and K‐feldspar). The deformation microstructures suggest that the HHLG was deformed under early high temperature ductile deformation conditions. These fabrics were subsequently superimposed by later brittle deformation features associated with decreasing temperatures during the exhumation of the HHLG towards shallow structural levels at the time of Himalayan orogeny.

MOS trench gate field-controlled thyristor

A novel device structure for a field-controlled thyristor (FCT) utilizing MOS trench gates (UMOS) to control the turn-off of the device is described. Two-dimensional computer modeling of static and dynamic characteristics was performed. This device exhibits a good forward conduction characteristic with a low forward voltage drop at high current densities. Simulation results on transient turn-off showed a turn-off capability of 500 A/cm/sup 2/ with the use of a reasonable gate bias. Experimental devices of the UMOS FCT were designed and fabricated. A turn-off current of 3.8 A with a very high turn-off current gain has been achieved. <<ETX>>
Using a CO2 laser for PIR-detector spoofing

This paper presents experimental work on the use of a CO2 laser for triggering of PIR sensors. Pyro-electric InfraRed sensors are often used as motion detectors for detection of moving persons or objects that are warmer than their environment. Apart from uses in the civilian domain, also applications in improvised weapons have been encountered. In such applications the PIR sensor triggers a weapon, when moving persons or vehicles are detected. A CO2 laser can be used to project a moving heat spot in front of the PIR, generating the same triggering effect as a real moving object. The goal of the research was to provide a basis for assessing the feasibility of the use of a CO2 laser as a countermeasure against PIR sensors. After a general introduction of the PIR sensing principle a theoretical and experimental analysis of the required power levels will be presented. Based on this quantitative analysis, a set up for indoor experiments to trigger the PIR devices remotely with a CO2 laser was prepared. Finally some selected results of the experiments will be presented. Implications for the use as a countermeasure will be discussed.
METHODOLOGICAL APPROACHES TO HEALTH RISK ASSESSMENT UNDER EXPOSURE TO CHEMICAL, PHYSICAL AND BIOLOGICAL FACTORS TO DETERMINE PRODUCT (GOODS) SAFETY INDICATORS

The publication focuses on the principle algorithm and methods to assess consumer products safety in terms of public health. The methodology is based on a standard risk assessment procedure including the following stages: hazard identification, exposure assessment, dose-response assessment, and risk characterization. The key feature of the developed approaches is the use of mathematical modeling to describe risk development based on the adjustment of paired 'factor (exposure) - response" relationships obtained in the course of epidemiological studies for the purposes of risk escalation assessment. A dynamic model of functional disorders associated with product safety is a mathematical description of the process of change in the state of health of consumers under long-term exposure to product-related hazardous factors combined with natural ageing. The publication describes approaches to the assessment of cumulative risk associated with various product factors, suggests risk structuring techniques and an international ly harmonized risk assessment scale. The methodology is universal, aimed for a wide range of objectives, and serves the purposes of the Customs Union. The methodology was tested when validating food product safety criteria in assessing the risks associated with such long-use products as furniture, construction and finishing materials.
ACTIVITY RECOGNITION FROM ACCELERATION DATA COLLECTED WITH A TRI-AXIAL ACCELEROMETER

This paper proposes a high accuracy classifier for human activity based on data collected with a single tri-axial accelerometer mounted on the right part of the hip. The accuracy of this classifier is very important for detecting the postures. Therefore we use methods like acceleration magnitude and neural network and compare them to find the best solution.
Multi‐decadal changes in phytoplankton biomass in northern temperate lakes as seen through the prism of landscape properties

Ecologists collectively predict that climate change will enhance phytoplankton biomass in northern lakes. Yet there are unique variations in the structures and regulating functions of lakes to make this prediction challengeable and, perhaps, inaccurate. We used archived Landsat TM/ETM+ satellite products to estimate epilimnetic chlorophyll‐a (Chl‐a) concentration as a proxy for phytoplankton biomass in 281 northern temperate lakes over 28 years. We explored the influence of climate (air temperature, precipitation) and landscape proxies for nutrient sources (proportion of wetlands in a contributing catchment, size of the littoral zone, potential for wind‐driven sediment resuspension as estimated by the dynamic ratio) or nutrient sinks (lake volume) in a random forest model to explain heterogeneity in peak Chl‐a. Lakes with higher Chl‐a (median Chl‐a = 2.4 μg L−1, n = 40) had smaller volumes (<44 × 104 m3) and were more sensitive to increases in temperature. In contrast, lakes with lower Chl‐a (median Chl‐a = 0.6 μg L−1, n = 241) had larger volumes (≥44 × 104 m3), contributing catchments with smaller proportions of wetlands (<4.5% of catchment area, n = 70), smaller littoral zones (<16.4 ha, n = 137), minimal wind‐driven sediment resuspension (as defined by the dynamic ratio; <0.45, n = 232), and were more sensitive to increases in precipitation. Lakes with larger volumes were generally less responsive to climate factors; however, larger volume lakes with a significant proportion of wetlands and larger littoral zones behaved similarly to lakes with smaller volumes. Our finding that lakes with different landscape properties respond differently to climate factors may help predict the susceptibility of lakes to eutrophication under changing climatic conditions.
A Model Predictive Control Algorithm Applied in T-type Three-level Power Conversion System

Model predictive control (MPC) has been widely used in grid-connected battery energy storage system. This paper addresses model power predictive control in T-type three-level power conversion system. A model predictive control algorithm based on T-type three-level converter is proposed. Compared to traditional neutral point clamped (NPC) three-level converter, T-type three-level converter suffers no output phase voltage jump limitation thus more outstanding performance by MPC can be achieved. This paper describes the model of T-type three-level converter as well as the principle of model predictive control algorithm. Moreover, a geometrical analysis method has been used to demonstrate that the performance of T-type converter is superior to NPC converter. The simulation results verify the feasibility of former analysis.
Healthcare, uncertainty, and fuzzy logic

Fuzzy nature of decision-making process in healthcare enforces technology producers and researchers to employ creative and smooth solutions. Conversion from fuzzy concepts and ideas to crisp values causes loss of precision and weakens the output decisions. A promising bundle of techniques, soft computing, is a fast developing and popular area that helps meet this creative and smooth need in healthcare. In this study, fuzzy logic (FL) application in healthcare decision-making is examined. The number of publications is rising each year related to FL application in healthcare. FL can be used as a classifier, or in a selection process of a certain type of disease, or diseased patients, or determining the risk ratio of a disease, or in a data mining algorithm, or in constructing a decision support system. This study is a descriptive study aiming to examine and explain FL applications in healthcare.
