Performance Evaluation of a GPRS/Bluetooth Diabetes Management System

Diabetes management has been playing an important role on preventing or delaying occurrence of the life threatening diabetes complications. By providing a roaming operation environment, mobile healthcare technologies can bring efficiencies and convenience to both diabetics and relative medics on diabetes management. This paper briefly introduces a system called MDMIS that operates across Bluetooth and live GPRS networks for pervasive diabetes management. As the major contribution of this work, a comprehensive study on system performance of MDMIS in real world networking environments is carried out. The main purpose of this study is to examine the quality of service of MDMIS for daily diabetes management. Experimental results show that the application of Bluetooth/GPRS in mobile disease management is feasible.
A Global Analysis of the Effect of Political Regime Changes on Life Integrity Violations, 1977-93

This study develops a model of different types of political regime changes and their effect on life integrity violations. The data cover 147 countries from 1977-93. A multivariate pooled cross-sectional time-series research design is used, employing Ordinary Least Squares regression with panel-corrected standard errors. This research focuses on different types of regime change that vary in direction and intensity. It tests the effect of political regime changes on life integrity violations at time t and at time t - 1. The results show that regime change in general does not alter the levels of repression. However, change from autocracy toward democracy decreases repression during the transition period, whereas change from democracy to anocracy increases life integrity violations. It is also shown that the higher the magnitude of democratization, the less state violence occurs during the year of the change, once relevant control variables are considered.
Patterns in strategic joint ventures of selected prominent cross-border contractors for 1999–2003

Scholars have noted that cross-border businesses have been increasingly using alternative forms of overseas involvement instead of going-it-alone. A study was conducted to document and subsequently identify possible patterns from the strategic joint ventures adopted by selected contractors that appeared in the Engineering News Record’s annual top 225 international contractors survey from 1999–2003 inclusively, which was also the framed study period. The modes of strategic joint ventures that became the focus of the study were equity joint venture companies, serial joint ventures, and long-term joint venture contracts. Data was collected entirely from secondary sources, which were triangulated to remove possible biases. The study found patterns in terms of frequency of the various modes, nationality of partners, markets the joint ventures served, and industries the partners belonged to. The findings add to our knowledge on the behaviour of cross-border contractors.
Risâletü'n-Nushiyye'de İletişim Fiilleri

Risâletü‟n-Nushiyye was written by Yunus Emre in masnavi genre. Besides its literary value and the language material it contains, it is also important in terms of being one of the first advice books in the Anatolian field. In this sufistic and didactic work, it is seen that communication verbs, which are included as one of the basic classes in verb classifications, come to the fore in some parts. Verb classification attempts have been made by many researchers according to the morphological, syntactic and semantic properties of verbs. In this study, the use of communication verbs included in the classification studies according to the semantic features of verbs in Yunus Emre's Risâletü‟n-Nushiyye will be discussed. The study will be based on Levin's work, which includes the communication verbs among 57 classes in which he separates the verbs according to their semantic features. In Levin's study, communication verbs is divided into nine groups as verbs of transfer of a message, tell, verbs of manner of speaking, verbs of instrument of communication, talk verbs, chitchat verbs, say verbs, complain verbs and advise verbs . In the study, verbs of praise were also added to these groups. The usage of these ten communication verb groups in Risâletü‟n-Nushiyye will be determined. Their dispersion in 6 chapters of Risâletü‟n-Nushiyye will be shown.
Nonlinear Dynamics of Endocrine Feedback in Hypothalamico-Pituitary-Ovarian (HPO) Axis and Its Prospective Role in Screening and Understanding Etiology of Ovarian Cancer

The idea of feedback mechanisms in endocrine medicine has remained ill conceived especially in the light of modern control theory where energy transfer is understood in a system wise fashion. The idea is based on reductionism i.e. describing function on a discrete molecular level whilst at the macro level the desired accuracy is not achieved. Endocrinology text books have even gone with this wind of discreteness, some have even drastically cut the subject to a bare minimum probably agreeing to the sanctity of its omnipotence. End product inhibition, regulatory enzymes, allosteric configuration changes and other physiological phenomena are examples of biological feedback mechanisms. It is not astonishing that modern control theory with all its mathematical facets has already gained a perceptible entry into the endocrinology literature. Applications of chaos theory in gynaecology and obstetrics were proposed in the early nineteen-eighties. Applications of biomathematics including nonlinear control theory is fast gaining ground and, like molecular biology in last decade can not be ignored anymore. For our understanding of hormone function to progress, endocrinological feedback mechanisms as part of gynaecological and obstetric assessment needs to be understood within complex systems science.
Design and implementation of a five-hp, switched reluctance, fuel-lube, pump motor drive for a gas turbine engine

A new switched reluctance (SR) fuel/lube (F/L) pump system has been developed for a gas turbine engine application. The system is rated at 5 HP, 270 V DC, 12.5 krpm maximum operating speed, and consists of a SR machine mounted on the F/L pump shaft, an inverter, and an electronic controller. This paper focuses on the design, implementation, and performance of the system. The system can use one of two methods for rotor position sensing, either a resolver or electronic position sensing (EPS). The F/L pump system has undergone extensive performance testing with the resolver. Testing is underway using electronic position sensing. Test results are given to validate the system design and compare the performance using both approaches to position sensing. System efficiency is about 82 percent at full load. >
Measurement Selections for Multi-Component Gas Path Diagnostics Using Analytical Approach and Measurement Subset Concept

Gas path analysis (GPA) is a powerful tool to predict gas turbine degradations based on measurement parameters of gas turbine engines. Accordingly, prudent measurement selections are crucial to ensure accurate GPA predictions. This paper is intended to investigate the influence of measurement parameter selection towards the effectiveness of GPA algorithm. An analytical methodology for measurement selection, combined with measurement subset concept, is developed to properly select measurements for multiple component fault diagnosis. The effectiveness of GPA using the measurement sets selected with the introduced measurement selection method are then compared to the results of using standard measurements installed on existing gas turbine engines. A case study applying the new measurement selection method to GPA diagnostic analysis is demonstrated on a 3-shaft aero-derivative industrial gas turbine model based on similar unit installed onboard an offshore platform operated by PETRONAS. The engine is modeled and simulated using PYTHIA, a gas turbine performance and diagnostics analysis tool developed by Cranfield University. To validate the findings, non-linear GPA prediction errors are evaluated in various cases of single and multi components faults. As a result, the selected measurements have successfully produced much superior diagnostics accuracies in the fault cases when compared to the standard measurements. These findings proved that proper measurement selection for better GPA diagnostic analysis can be achieved by using the proposed analytical methods. Several engine sensor enhancements are also discussed to accommodate the unique sensor requirements for health diagnostics using GPA.Copyright © 2010 by ASME
Fractal Model Developed for Elliptic Elastic-Plastic Asperity Microcontacts of Rough Surfaces

An elastic-plastic asperity fractal model for analyzing the contact of rough surfaces is presented. Instead of using the power-law relation, which is widely used to predict the number, N, of contact spots with the area larger than the area of a' in per unit apparent area, the size-distribution functions valid in the elastic, elastoplastic, and fully plastic deformations have been individually developed in the present model for contact surfaces with elliptic asperities. These three size-distribution functions can be used in the calculations of the N value. The error in the number N, which exists between the results predicted by the present model and those obtained from experiments, is greatly reduced as compared with the error arising between the experimental results and those predicted by the power-law model. If the topothesy, G, and the fractal dimension, D, of contact surfaces are properly chosen to conform to those given plasticity indices, the results predicted by the present model are considerably closer to that predicted by one published study. Changes in the ellipticity parameter of contact spots may introduce a substantial difference in the relationship established for the real contact area and the total load.
Enemy or ally: a genomic approach to elucidate the lifestyle of Phyllosticta citrichinaensis

Members of the fungal genus Phyllosticta can colonize a variety of plant hosts, including several Citrus species such as Citrus sinensis (orange), Citrus limon (lemon), and Citrus maxima (pomelo). Some Phyllosticta species have the capacity to cause disease, such as Citrus Black Spot, while others have only been observed as endophytes. Thus far, genomic differences underlying lifestyle adaptations of Phyllosticta species have not yet been studied. Furthermore, the lifestyle of Phyllosticta citrichinaensis is ambiguous, as it has been described as a weak pathogen but Koch’s postulates may not have been established and the presence of this species was never reported to cause any crop or economic losses. Here, we examined the genomic differences between pathogenic and endophytic Phyllosticta spp. colonizing Citrus and specifically aimed to elucidate the lifestyle of Phyllosticta citrichinaensis. We found several genomic differences between species of different lifestyles, including groups of genes that were only present in pathogens or endophytes. We also observed that species, based on their carbohydrate active enzymes, group independent of their phylogenetic association, and this clustering correlated with trophy prediction. Phyllosticta citrichinaensis shows an intermediate lifestyle, sharing genomic and phenotypic attributes of both pathogens and endophytes. We thus present the first genomic comparison of multiple citrus-colonizing pathogens and endophytes of the genus Phyllosticta, and therefore provide the basis for further comparative studies into the lifestyle adaptations within this genus.
High-power-factor operation of three-phase ac-to-dc resonant converter

Analysis and design of a three-phase AC-to-DC resonant converter is considered. The power factor of the three-phase AC input line diode bridge rectifier is improved by injecting high-frequency current. The three-phase AC-to-DC resonant converter is operated at frequencies above the resonant frequency. The analysis of the converter is carried out using different operating modes in one switching cycle of the resonant inverter. The design of the AC-to-DC resonant converter is discussed step by step. An experimental prototype of a 3 kW, 500 V output power and operating above 300 kHz has been developed in the laboratory. The proposed three-phase AC-to-DC resonant converter has high power factor, low total harmonic distortion and high efficiency. It requires narrow variation in switching frequency to regulate the output voltage
Development of 1.5 THz waveguide NbTiN superconducting hot electron bolometer mixers

We present a characterization of a 1.5 THz waveguide niobium titanium nitride (NbTiN) superconducting hot electron bolometer (HEB) mixer which can be pumped by a commercial solid state tunable local oscillator (LO) source. The NbTiN HEB mixer is made from a 12 nm thick NbTiN thin film deposited on a quartz substrate at room temperature. A gold electrode is formed in situ on the NbTiN thin film without breaking vacuum to ensure good contact. The uncorrected DSB receiver noise temperature is measured to be 1700 K at 1.5 THz, whereas the mixer noise temperature is derived to be 1000 K after corrections for losses of the input optics and the intermediate frequency (IF) amplifier chain. The required LO power absorbed in the HEB mixer is evaluated to be 340 nW by using an isothermal technique. The IF gain bandwidth is supposed to be about 1.3 GHz or higher. The present results show that good performance can be obtained at 1.5 THz even with a relatively thick NbTiN film (12 nm), as in the case of 0.8 THz. In order to investigate the cooling mechanism of our HEB mixers, we have conducted performance measurements for a few HEB mixers with different microbridge sizes both at 1.5 and 0.8 THz. The noise performance of the NbTiN HEB mixers is found to depend on the length of the NbTiN microbridge. The shorter the microbridge is, the lower the receiver noise temperature is. This may imply a contribution of the diffusion cooling in addition to the phonon cooling.
Towards a theory of construction as production by projects

This paper responds to the invitation to debate the theory of production in construction from the advocates of lean construction. In particular, it is a response to Koskela and Ballard's critiques of the theory of project management represented in the Project Management Institute's (PMI) PMBoK, and the ‘economics-based’ approach to construction project management presented by Winch. The paper reviews the theoretical and practical contributions of lean construction before addressing the specific criticisms made. It then suggests that lean construction theory has its own limitations and requires further development in the areas of the definition of process, the concept of organization, the theorization of risk and uncertainty, and its unitary concept of value. Cet article est la réponse des défenseurs de la construction « au plus juste » lorsqu'ils ont été invités à la théorie de la production dans la construction. Il réagit, notamment, aux critiques de Koskela et Ballard sur la théorie de la gestion de projet représentée dans le PMBoK du Institut de Gestion de Projet et à l'approche basée sur l'économie de la gestion de projets de construction présentée par Winch. Cet article passe en revue les contributions théoriques et pratiques de la construction ‘au plus juste’ avant de traiter des critiques spécifiques faites à ce sujet. Il suggère ensuite que la théorie de la construction ‘au plus juste’ a ses propres limites et nécessite d'autres développements dans les domaines de la définition des procédés, du concept d'organisation, de la théorie des risques et des incertitudes et de son concept unitaire de la valeur. Mots clés: construction ‘au plus juste’, gestion de projet, gestion des risques, économie des coûts des transactions, incertitude, valeur

RANCANG BANGUN SISTEM INFORMASI PAYROLL DAN LAPORAN PPH 21 BERBASIS DESKTOP PADA PT CATERPILLAR INDONESIA BATAM

The development of information technology has created convenience and accuracy in decision making within government agencies and companies. The problem that often arises in a company is about the payroll system, this is a lot we see in electronic and print media there are employees who do demos to demand an increase in salary and no transparency in payroll. The use of computers in any company is very common and ordinary, because there are already many and even all companies use computers as a medium for storing data and controlling data. But the data storage system is still manual for example with Ms. Excell is still lacking in data storage systems. Where so far the recording of the salary of employees is still using the manual system. Given the payroll in a company is an important thing and requires proper handling so that there are no errors in the calculation of employee work hours or extra hours / overtime hours, so we need a system that can overcome these problems. Using VB.Net 2008 Programming can help in making reports that are fast, accurate, timely and also eliminate the constraints that exist in making salary data reports.
Space-time processing for multichannel synthetic aperture radar

Synthetic aperture radar (SAR) provides high-resolution images of a non-moving ground scene, but fails to indicate the presence and position of moving objects. As in airborne MTI (moving-target indication) systems the solution to this problem is to use an array of antennas or subapertures and several receiving channels ('MSAR', or multichannel SAR), and to apply multichannel clutter suppression. One of the most efficient methods is adaptive space-time processing (STAP), which can be simplified to frequency-dependent spatial processing in the Doppler domain. Some of these techniques applied to SAR are reviewed and illustrated with data gathered by the German experimental multichannel SAR system 'AER-II'.
A New Decision Making Model for Subcontractor Selection and Its Order Allocation

All experts agree on the importance of subcontracting. The high impact of subcontractors on the construction process means that the selection of subcontractors is a sensitive activity. Previous investigations documented the selection of subcontractors based on criteria but did not consider the number of subcontracted tasks. This paper explores allocating the best portion of tasks to subcontractors while optimizing the risk and cost in the fixed project schedule. The study's main finding demonstrates that subcontractor selection without attention to the order allocation is not a realistic approach; therefore, a hybrid model that applies continuous ant colony and fuzzy set theory is proposed.

Power Quality of Grid-Connected Wind Turbines with DFIG and Their Interaction with the Grid

A simulation model of a MW-level wind turbine with dynamic slip control and pitch control is developed in the simulation tool of PSCAD/EMTDC and stability investigations are carried out with respect to a short circuit fault in the external power system. After the fault has been cleared, the voltage at the wind turbine terminal has to be re-established, and the wind turbine should restore its normal operating condition. Controlling the generator slip and pitch angle can adjust the electromagnetic torque and the aerodynamic torque of wind turbine, which helps to rebuild the voltage at the wind turbine terminal. Simulation results prove that dynamic slip control and pitch control are effective methods to improve the voltage and maintain power system stability.
THE CHANGE OF KNEE KINEMATICS AFTER ANTERIOR CRUCIATE LIGAMENT DEFICIENCY AND RECONSTRUCTION DURING LANDING

The purpose of this study were to evaluate the different of knee kinematics analysis after ACLD and ACLR during landing performances. The participants were instructed to finish counter moment jump (CMJ) with arms free 5 times as hard as possible with Vicon motion system and two force platforms. The ACLD showed a significant less knee flexion degree at the peak vertical GRF compared with others. Our founding was similar to the present studies; the impulse during landing among three groups was almost the same, but the RF EMG showed lower after two ACL groups, especially in ACLD.

According to Neil Gershenfeld, the renowned MIT scientist and inventor, the next big thing is personal fabrication-the ability to design and produce your own products, in your own home, with a machine that combines consumer electronics and industrial tools. Personal fabricators are about to revolutionize the world just as personal computers did a generation ago, and Fab shows us how.
Cell Separation Through Ascending and Descending Curvilinear Microchannels

Separation of rare cells such as fetal cells from blood has potential importance in disease investigation and prevention. In this paper we report a new method of cancer cells separation from patient’s blood by inertial focusing technique. A design and simulation of ascending and descending curvilinear microchannels for separation of particles resembling cancer cells have been presented. Computational fluid dynamics (CFD) design and simulation of ascending and descending microchannels is used for cell separation. The simulation was carried out in two stages including focusing and separation. The ascending curvilinear channel design demonstrated favorable focusing and separation. Separation with 100% purity and efficiency of the unwanted particle was achieved at Reynolds number (Re) = 8.50 and velocity 0.105m/s. Reynolds number 9.25 and 10.06 with corresponding velocities 0.115 m/s and 0.125 m/s were also investigated for cell seperation. In case of descending curvilinear channel, cell separation was not good. Considering cancer cells size about 15 µm, our proposed ascending microchannel is a good candidate for cancer cells separation from blood.
