Unloaded Qs of axially asymmetric modes of dielectric resonators

The resonant frequencies and unloaded Qs of hybrid modes on cylindrical dielectric resonators in conducting enclosures are studied. The formulation uses the mode-matching technique and includes axially symmetric (TE/sub 0m/ and/or TM/sub 0m/), as well as axially nonsymmetric hybrid (HE/sub nm/) modes, which could exist in dielectric-loaded waveguides. The structures analyzed can simulate resonators on microstrip substrates. The losses in both the conducting walls and the dielectric material and the stored energy in the general resonator are obtained. Mode amplitudes determined from the solution of the boundary value problem by mode matching are used to rigorously compute the unloaded Qs of the resonators. Numerical results in the millimeter-wave range are presented for the unloaded Qs of various modes as a function of the resonator parameters. The effects of losses on the resonator wall are discussed, and methods of improving the unloaded Qs are explored. The method was applied to a 33 GHz resonator on GaAs, alumina, and quartz substrates, and the results verify the accuracy of the model used and the numerical computations. <<ETX>>
Prefabrication as a mean of minimizing construction waste on site

Construction waste has become a major source of solid waste in Hong Kong. Thousands of tons of solid waste is produced every year from construction and demolition activities. Increasing generation of this waste has caused significant impacts on the environment and aroused public concerns. Therefore, minimization of construction waste has become a pressing issue. This paper aims to (i) reveal the status of construction waste, (ii) investigate the effectiveness of prefabrication in terms of waste reduction in replacing the traditional on-site production, (iii) examine the factors that help minimizing construction waste by the adopting prefabrication and (iv) explore the areas of waste reduction after adoption of prefabrication in comparison to traditional on-site production. The findings of a structured survey show that waste from ‘poor workmanship’ can be greatly reduced by adopting prefabrication in construction. Furthermore, after the adoption of prefabrication, waste generation can be greatly reduced in various on-site production activities, including plastering, timber formwork, concreting and reinforcement, with 100% waste reduction seen in plastering. Case studies are also used to demonstrate the effectiveness in the use of prefabrication to minimize construction waste in Hong Kong. It can be concluded that using prefabrication of building components is one of the most effective technologies of waste minimization.
Corporate Governance and Financial Performance: A Comparative Study of South East Asia’s Hospitality Industries

The aim of this research is to examine financial performance of hospitality companies from Indonesian, Malaysia, and Thailand. This research also examines the relationship between two aspects of corporate governance, i.e. transparency and independence, and financial performance. Transparency is proxied by environmental disclosure and social disclosure, while independence is identified by the proportion of independent board commissioner and proportion of audit committee independence. The population of this research covers secondary data from Hospitality Company annual reports in 2012-2014 obtain through Indonesia Stock Exchange (IDX), Bursa Malaysia and The Stock Exchange of Thailand (SET). The sample of this research contains 72 hospitality companies in Indonesia, Malaysia, and Thailand that generated using purposive sampling method. The result shows that there are no differences in the financial performance between hospitality companies in Indonesia, Malaysia, and Thailand. Multiple regression analysis shows mixed results. Environmental disclosure and social disclosure both have a significant effect on financial performance. However, the proportion of independent commissioner has no significant effect on financial performance. On the other hand, the proportion of audit committee independence significantly affects financial performance.
MONITORING THE WEAR-LINE OF A MELTING FURNACE

The paper includes a description of different strategies for monitoring the wearline of a melting furnace. This type of industrial monitoring is important for both economic and safety reasons. Temperature sensors at different locations in the lining of the furnace combined with an inverse heat conduction model are utilized for monitoring the state of the lining. The wearline boundary is represented by a critical isotherm, and the estimation of this isotherm is the crucial part of the inverse solution. Two numerical algorithms for the inverse problem are described. The algorithms are tested on model data as well as on measurement data acquired at an industrial furnace. One algorithm is based on utilizing a fix ed boundary with controlling nodes, on the wearline side, to approximate the measurements. The other algorithmic approach is to approximate the wearline as close as possible with as few curve representing parameters as possible. Both algorithms utilize the common approach of minimizing the sum of the squared residual at the sensor locations. We also report on some limited numerical sensitivity studies for the algorithms. The numerical experiments confirm the utility of the algorithms as the results are in good agreement with test model data as well as industrial data.
FROM FRACTURES TO FRAMES: CONFLICT REPORTING IN NEWSPAPERS OF ASSAM

The Northeast region of India has been marked by sustained separatist insurgencies, mass agitations and ethnic conflicts. This region has been the setting for the earliest and longest lasting insurgency in the country. Subject to ‘various brands of identity politics’ ever since the colonial days, leading to exclusion and deprivation, the region’s history of violence can be seen as a powerful manifestation of its vehemence to preserve its identity.This ‘identity crisis’ which is considered to be the core cause of bloodshed in the region, has been the subject of dissection by a number of academicians as well as journalists. The identity crisis in the region manifests itself in two major forms of identity movements – (1) Independence movements for autonomy or self-rule and (2) Movements for ousting of foreigners/ outsiders from their ‘mother land’. Like other ethnic groups in the regions, the Bodos too have a long history of such identity crusades – beginning with the movement for Bodoland dating back to the 1960s to the more recent instances of resisting immigrant settlers, both from Bangladesh and from other regions of India, even Assam. The two latest incidents of conflict involving the Bodos represent resistance to two distinct groups of ‘outsiders’: The July– September, 2012 conflict between the native Bodo community people and the Muslim settlers which eventually took shape into one of the bloodiest instances of ethnic violence in Assam, left over 90 people dead and 400,000 displaced. The more recent December 2014 BodoAdivasi conflict fired up due to terror attacks by the National Democratic Front of Bodoland (Songbijit) on Adivasi villages on the night of December 23 triggering a humanitarian crisis. Scores of innocents including children lost their lives and lakhs of people had to take shelter in make-shift relief camps.Both these incidents received widespread coverage in the media – both local and national media. The objective of this study is to compare the coverage of the 2012 Bodo-Muslim violence in the two leading English and vernacular dailies in Assam over a two month period with reference to the standards of conflict sensitive journalism and sensitivity towards communal harmony. Using framing analysis, the present enquiry also attempts to understand the prominent frames used by the newspapers while reporting the issue.

The resonant gate transistor

A device is described which permits high- Q frequency selection to be incorporated into silicon integrated circuits. It is essentially an electrostatically excited tuning fork employing field-effect transistor "readout. " The device, which is called the resonant gate transistor (RGT), can be batch-fabricated in a manner consistent with silicon technology. Experimental RGT's with gold vibrating beams operating in the frequency range 1 kHz 0 Q 's as high as 500 and overall input-output voltage gain approaching + 10 dB have been constructed. The mechanical and electrical operation of the RGT is analyzed. Expressions are derived for both the beam and the detector characteristic voltage, the device center frequency, as well as the device gain and gain-stability product. A batch-fabrication procedure for the RGT is demonstrated and theory and experiment corroborated. Both single- and multiple-pole pair band pass filters are fabricated and discussed. Temperature coefficients of frequency as low as 90- 150 ppm/°C for the finished batch-fabricated device were demonstrated.
Automatic Recognition of Fake Profiles on Social Media: A Survey

— At present social network sites are part of the life for most of the people. Every day several people are creating their profiles on the social network platforms and they are interacting with others independent of the user’s location and time. The social network sites not only providing advantages to the users and also provide security issues to the users as well their information . Fake accounts are a preferred means for malicious users of online social networks to send spam, commit fraud, or otherwise abuse the system. A single malicious actor may create dozens to thousands of fake accounts in order to scale their operation to reach the maximum number of legitimate members. Detecting and taking action on these accounts as quickly as possible is imperative in order to protect legitimate members and maintain the trustworthiness of the network. However, any individual fake account may appear to be legitimate on first inspection, for example by having a real-sounding name or a believable profile. In this literature survey, we review the existing research work done on Facebook, and study the techniques used to identify and analyze poor quality content on Facebook, and other social networks. We also attempt to understand the limitations posed by Facebook in terms of availability of data for collection, and analysis, and try to understand if existing techniques can be used to identify and study poor quality content on Facebook.
Effect of Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) Infestation on Wheat Flour Quality at Different Temperatures

Tribolium castaneum is one of the most destructive insects infesting cereals and their products worldwide. The quality changes of wheat flour infested by initial 0 (as a control), 2, 4, 6, and 8 adults of T. castaneum in 500 g wheat flour were investigated at 15, 25, and 30°C after different storage periods. The quality of wheat flour changed little during 150 d storage at 15°C, but it significantly decreased with increasing initial insect density and storage time during 150 d storage at 25 and 30°C. The moisture content, fatty acid value, falling number, and protein content of wheat flour were 12.21±0.19%, 190.08±3.51 mg KOH (100 g), 208.67±7.23 s, and 14.25±0.02% after 30 d storage at 30°C, respectively. The wet gluten content and dry gluten content of wheat flour could not be detected after 90 d storage at 25 and 30°C. These results provide useful information for maintaining wheat flour quality.
Detection of Malicious Command Injection Attacks on Phase Shifter Control in Smart Grids

—Phase shifters (or phase shifting transformers) are used in power grids to regulate the ﬂow of real power. They are used to prevent overloading of transmission lines and also to regulate cross-network power ﬂows as per contractual obligations. In a smart/automated grid, these phase shift commands are relayed through SCADA networks. As a result, this control is vulnerable to cyber attacks, especially stealthy ones. Malicious phase shift commands can severely overload critical transmission lines, resulting in their disconnection, and also cause ﬁnancial losses by disrupting cross-network trading. The protection of this control from cyber attacks, though crucial, has not received any attention in literature. This paper is the ﬁrst which considers such attacks and proposes a method/algorithm to detect them, including the stealthy ones (which beat bad data detection). The proposed algorithm is based on indices that are ratios of branch or node injection currents to the terminal voltages. The effectiveness of these indices (in the context of detection) is validated mathematically. These indices are used to formulate the proposed algorithm which is found to be reliable, computationally light and easy to implement when tested on phase shifters placed in the IEEE 118-bus system. As the proposed algorithm is based on the principles of power system analysis, it is usable under any network technology.
Common-Mode Noise Reduction in Wide Band Gap Device Based Motor Drives

Wide band gap (WBG) devices are the latest trend in the power electronics industry. MOSFETs built using WBG materials offer numerous benefits to power electronic circuits. The various benefits of WBG based devices are apparent at breakdown voltages ≥ 600V, where Silicon IGBTs are typically used due to their combination of high breakdown voltage and low conduction losses. Compared to Silicon IGBTs, WBG MOSFETs offer faster switching rates, which reduces switching losses while also enabling significantly higher switching frequencies. This thesis will explore the application of WBG MOSFETs to motor drives, where higher switching frequencies reduce motor losses and torque ripple and allow higher control bandwidth, thus enabling greater output frequencies needed to operate motors at higher speeds. It is well known that common-mode voltage (CMV) is generated in pulse width modulated (PWM) based drives. These voltages are responsible for bearing deterioration, shaft voltage build up and electromagnetic interference (EMI). Various software techniques like space vector modulation provide reduction in common-mode voltage. Hardware solutions like shielded cables, common-mode filters etc. also reduce common-mode currents. Hence for analyzing the effects of shaft voltage and common– mode currents, two-level voltage source inverters (VSI) utilizing Silicon Carbide (SiC) MOSFETs are constructed to operate a 1 HP induction motor. Experimental results are presented which show that the short turn-ON and turn-OFF transients as well as high switching frequencies lead to increased shaft voltage and ground currents. Elimination of ground currents is necessary to increase the lifetime of the bearings. Mitigation techniques of open-end winding drive and clamp-on ferrite chokes are evaluated in this thesis. The shaft voltage and ground currents are found to be best suppressed in an open-end winding drive utilizing clamp-on ferrites. Simulation results of loss analysis is presented for a conventional two-level VSI and dual two-level VSI to understand the thermal requirements of the Si and SiC based drives. The advantages and disadvantages of WBG based conventional two-level inverter and the various mitigation techniques are discussed.

Robot Trotting with Segmented Legs in Simulation and Hardware.

This research is focusing on the implementation, testing, and analysis of quadrupedal, bio-inspired robot locomotion. Our tool of research is a light-weight, quadruped robot of the size of a house cat, both in simulation and hardware. We are currently following the idea of testing bio-inspired blue-prints such as leg-segmentation, directional leg compliance (bio-mechanical), and central pattern generators (bioinspired neuro-control) for their feasibility, and advantages against more traditional, engineered solutions. Clearly, our ﬁrst goal would be to reach a same level of performance as animals, e.g. in terms of speed, cost of transport, or versatility. Much research has been done on bio-mechanical and neuro-physiological research on legged vertebrates. Hence, data is available for animal locomotion such as gait patterns, speed, cost of transport, duty factor, joint angles, torque patterns, body angles, and ground reaction force (GRF) data. While this data allows one to study a subset of locomotion characteristics, it often lacks an intuitive way to compare animals of different species, or as for us, quadruped robots. We started applying the collision angle analysis (Lee, Bertram, et al. 2011) for trot gait, based on qualitative and quantitative results from goats and dogs (taken from (ibid.)), and experimental recordings of our robot’s center of mass (COM) and GRF.
Propionate alleviates myocardial ischemia-reperfusion injury aggravated by Angiotensin II dependent on caveolin-1/ACE2 axis through GPR41

Myocardial ischemia/reperfusion (I/R) injury is still a lack of effective therapeutic drugs, and its molecular mechanism is urgently needed. Studies have shown that the intestinal flora plays an important regulatory role in cardiovascular injury, but the specific mechanism has not been fully elucidated. In this study, we found that an increase in Ang II in plasma was accompanied by an increase in the levels of myocardial injury during myocardial reperfusion in patients with cardiopulmonary bypass. Furthermore, Ang II treatment enhanced mice myocardial I/R injury, which was reversed by caveolin-1 (CAV-1)-shRNA or strengthened by angiotensin-converting enzyme 2 (ACE2)-shRNA. The results showed that CAV-1 and ACE2 have protein interactions and inhibit each other's expression. In addition, propionate, a bacterial metabolite, inhibited the elevation of Ang II and myocardial injury, while GPR41-shRNA abolished the protective effects of propionate on myocardial I/R injury. Clinically, the propionate content in the patient's preoperative stool was related to Ang II levels and myocardial I/R injury levels during myocardial reperfusion. Taken together, propionate alleviates myocardial I/R injury aggravated by Ang II dependent on CAV-1/ACE2 axis through GPR41, which provides a new direction that diet to regulate the intestinal flora for treatment of myocardial I/R injury.
RAUIELLA THUIDIOIDES , SP . NOV . ( LESKEACEAE , BRYOPHYTA ) , A NEW SPECIES FROM THE RUSSIAN FAR EAST RAUIELLA THUIDIOIDES

Molecular barcoding of a morphologically unfamiliar thuidiaceous moss, known so far from two specimens collected in the Sikhote-Alin mountain range suggested the affinity with the genus Rauiella. Subsequent evaluation in a broader phylogenetic context of Leskeaceae s. lat. using nuclear ribosomal ITS and chloroplast trnF-trnS regions confirmed that the plants which morphologically substantially differ from known representatives of Rauiella are molecularly likewise distinctive. It is therefore described and illustrated here as a new species, Rauiella thuidioides. We further discuss the morphological differences from its congeners and other similar taxa, as well as its ecology and geographical affinities. Finally, we also touch the delimitation of the genus Rauiella and advocate the synonymy of Thuidiaceae with Leskeaceae.
A Numerical And Experimental Analysis Of Laminar Flame Speed For Pre-Mixed Iraqi Lpg/Air Mixture In A Horizontal Cylindrical Combustion Chamber

In the present work, a numerical and an experiential study is performed to obtain the laminar flame speed for premixed Iraqi LPG-air mixture at different equivalent ratios ranging from 0.6 to 1.4 in a horizontal cylindrical combustion chamber. A horizontal Pyrex cylindrical with dimension (1300 mm) length with (180mm) diameter is used as combustion chamber. The entrance of fuel/air mixture and the ignition source are located at one end of the cylinder while the other end is left open. A high-speed camera is used to record the flame propagation through the cylinder. These videos are then analyzed using Tracker program to obtain the laminar flame propagation speed. Also the Chemkin USC mech 2.0 is used to predict numerically the flame speed. Both experimental and numerical results show that the flame speed increases with equivalence ratio and reaches its maximum value at stoichiometric ratio and decreases as the mixture becomes richer. The study also includes a numerical analysis of the effect of propane/butane ratio on the flame speed. The result shows that high propane ratio enhances flame speed.
Wavelength-interleaved OADMs incorporating optimized multiple phase-shifted FBGs for fiber-radio systems

We demonstrate that a single fiber Bragg grating (FBG)-based optical add-drop multiplexer can be used to improve the optical spectral efficiency in a mm-wave WDM-fiber wireless network. The technique employs wavelength interleaving in conjunction with optical single-sideband modulation, together with a single multiphase-shifted fiber Bragg grating. Wavelength optical add-drop features are also demonstrated using the grating, and our results show the performance of the novel grating in terms of channel isolation and add-drop functionality. We perform simulations to optimize placement of the phase shifts when an apodization profile is applied to the grating, in an attempt to minimize in-band and out-of-band transmission-amplitude ripples. Experiments are performed using cascade configurations both with the apodized gratings with optimal phase-shift positions and with the original unoptimized gratings. The experimental results demonstrate how these novel gratings can be used in fiber-radio networks incorporating multiple optical add-drop multiplexers.
