Autonomous biomimitic robot based multi-agent system for disaster management and rescue

This paper discusses the scope and feasibility of autonomous biomimitic robot based multi-agent systems for disaster management and rescue. Search and rescue operations in disastrous situations like earthquake, landslide, fire hazards, mineshaft breakdown etc. are still handled manually. Manual operations in these cases often fail due to complicated nature of the catastrophe. Especially in the case of human entrapment in areas inaccessible to either human or traditional rescue equipment. As such rescue operation suffers from improper strategy and even leads to unintentional further destruction due to lack of proper information along the rescue site. It is clear, proper information in and around the disaster can help successful handling of the catastrophe. Thus information like location of the survivor, state of the obstructions around him/her, state of injury, level of oxygen and hazardous gases are of crucial importance. To gather such widespread information from such difficult terrain, autonomous robots equipped with multiple sensors and capable to move inside difficult to access areas is a good choice. Autonomous biomimitic robot like Snake robot is meant to mimic motion of a natural snake, which does not possess any limb. Natural snakes can undergo wide range of motion and are able to move over rough terrains without the danger of entanglement. Slender structure of the snake body helps a snake to go inside narrow holes. Thus a snake robot able to mimic these features of a natural snake will be of extreme use in handling search and rescue operations. Snake robots equipped with multiple sensors and controlled under multiagent collaborative protocol are expected to bring about acceptable solution to disaster management and rescue. The other such biomimitic robots that can be considered in the autonomous robot team are flapping wing flyers and robot Monkeys. A team consisting of such robots will help in collecting information, distributing food and medicine in disastrous location.
6 – Textile product design analysis and modeling

: Design analysis is essentially a decision-making process in which analytical tools derived from basic sciences, mathematics, statistics and engineering fundamentals are utilized to develop a product model that can be converted into an actual product. The type of analysis required will depend on the product concept established, the specifications of the actual product intended and the application(s) in question. Common analytical tools used in design analysis are examined. The discussion is restricted to the principle of the analytical tool and potential applications in fiber-to-fabric engineering. Many examples of fibrous products are used to illustrate the principles of these analytical tools.
Автономные теплоэнергетические комплексы с альтернативными источниками энергии для нефтегазовой отрасли

Theoretical bases for creation self-contained heat-and-power engineering complexes with fuel and energy resources and with alternative energy sources, in particular with renewable energy sources that can be applied in oil-and-gas industry are elaborated. Formulas for calculation power and exergy efficiency of self-contained heat-and-power engineering complexes are offered in the work. The calculations have shown that power efficiency with renewable energy sources is not lower than the use of fuel and energy resources, and the application of waste energy allows increasing it on 20-30 %. The most thermodynamic and effective variant of self-contained heat-and-power engineering complexes with several alternative energy sources and its exergy efficiency exceeds exergy efficiency of self-contained heat-and-power engineering complexes with fuel and energy resources in 1,5-1,8 times. Original helio-plants, wind-energy plants and biogas plants allow to reduce the cost price of received thermal energy in 1,3-2,0 times. On the basis of power, exergy and technical and economic analysis the optimum variant for a given concrete consumer of self-contained heat-and-power engineering complexes with alternative energy sources can be created.
Fluid coupling and waves in the cochlea

The cochlea plays an important role in human hearing. Its basic function is to map sounds of different frequencies onto corresponding characteristic positions on the basilar membrane, BM. When sounds enter the fluid-filled cochlea, deflections of the BM occur due to pressure differences between the cochlear fluid chambers. These deflections propagate along the cochlea to a frequency-dependent characteristic position and then decay away rapidly. The mechanics of the cochlea are modelled using both analytic and numerical models. In this thesis, the passive response of the cochlea is analysed, corresponding to its behaviour at high sound levels, to study the fluid coupling and waves in the cochlea. The fluid coupling is studied in 1D and 3D, uniform and non-uniform, uncoiled and coiled geometries, all with a passive basilar membrane. A ‘uniaxial model’, which is dependent on only a single dimension, is developed to represent the three-dimensional cochlea. The finite element method is also used to provide an independent check of the results from the analytic model. Analytic methods are used to predict waves due to different mechanisms in the passive cochlea, such as 1D and 3D fluid coupling and longitudinal BM dynamics. The wave finite element, WFE, method is then used to decompose the results of a full finite element model of the coupled cochlea into wave components. Results show that apart from the conventional slow wave, other additional types of wave in the passive cochlea do not appear to play a dominant role in normal passive cochlear function.
Cost Effectiveness Trade-Offs in Software Support Environment Standardization.

Abstract : The objective of the research was to prepare an econometric model to determine quantitative benefits to the Air Force of implementing various strategies for controlling integrated automated software support environments. The model had to help the Air Force quantify costs and benefits obtainable by various methods of increasing productivity of developing and supporting mission-critical software. The principle deliverable is an econometric model describing costs and benefits involved in using Ada-based software development/support environments in DoD and contractor organizations. It is designed to permit comparisons among a selection of such environments. The model consists of econometric equations that describe actions required, and effects expected, during implementation. The equations were developed to describe decision-making as it typically takes place within AFSC. Keywords: MCCR computer program; MCCR (mission critical computer resources).

Identifying possible Stratification phenomenon in ionospheric F2 Layer using the data observed by the Demeter satellite: Method and Results

Abstract. Many studies have revealed the stratification phenomenon of the topside ionospheric F2 layer using ground-based or satellite-based ionograms, which can show direct signs of this phenomenon. However, it is difficult to identify this phenomenon using the satellite-based in situ electron density data. Therefore, a statistical method, using the shuffle resampling skill, is adopted in this paper. For the first time, in situ electron density data, recorded by the same Langmuir probe onboard the Demeter satellite at different altitudes, are analyzed and a possible stratification phenomenon is identified using the proposed method. Our results show that the nighttime stratification, possibly a permanent phenomenon, can cover most longitudes near the geomagnetic equator, which is not found from the daytime data. The arch-like nighttime stratification decreases slowly on the summer hemisphere and thus extends a larger latitudinal distance from the geomagnetic equator. All results, obtained by the proposed method, indicate that the stratification phenomenon is more complex than what has previously been found. The proposed method thus is an effective one, which can also be used on similar studies of comparing fluctuated data.
Operative Mitralklappenrekonstruktion

ZUSAMMENFASSUNG Die Mitralklappeninsuffizienz (MI) gehört neben der Aortenklappenstenose zu den häufigsten Klappenfehlern in den westlichen Ländern. Man unterscheidet je nach Pathologie zwischen der primären (degenerativen) und der sekundären (funktionellen) MI. Für die degenerative MI ist der therapeutische Goldstandard die chirurgisch-klappenerhaltende Korrektur des entsprechenden Klappenfehlers. Durch die Modernisierung der Herzchirurgie hat sich in den letzten Jahren zunehmend der Trend in Richtung minimal-invasiver Eingriffe gewandelt. Die in den letzten Jahren vorgestellten Methoden unterscheiden sich hauptsächlich im Zugangsweg. Der rechtsseitige anterolaterale Zugang ist aufgrund der guten Sicht auf die Mitralklappe inzwischen sowohl national als auch international als minimal-invasiver Zugang der Wahl etabliert. In wenigen spezialisierten Zentren wird darüber hinaus der videoassistierte total-endoskopische Zugangsweg mit exzellenten Ergebnissen angewendet.
Optimal characteristics of inserted graphic objects in stimulating CCTV operator vigilance and performance

images which rely more on interpretation (Familant & Detweiler, 1993) and learning (McDougall et al., 2001). Concrete images have more direct connections to objects in the real world and share characteristics with their referent objects (Familant & Detweiler, 1993). This allows people to apply their knowledge of the world to concrete images through mental representations or schemas. When people are unfamiliar with abstract images, they

Predictability of consecutive measurements of serum Anti-Mullerian Hormone (AMH) during In Vitro Fertilization (IVF)

Background : In recent years, many studies had been carried out on the basal AMH level and its association with controlled ovarian hyperstimulation (COH) outcome. Only a few studies have been conducted on the correlation between COH outcomes and AMH levels measured on different stimulation days and these studies did not show a comparison between different measurement timings over the entire period of the COH cycle. Objectives: the current study aim is to assess the predictive values of basal and consecutive serum AMH levels during COH cycle. Methods and Results: One hundred women were involved in this study, scheduled for IVF program in Dwarozh Fertility Center in Sulaimanyiah , between December 2015 until January 2017, blood samples were collected for measurement of AMH, Estradiol, and FSH on day 2 of menstrual cycle, and the subsequent samples on day 4,6,8 and 10 were taking after the stimulation of ovaries with gonadotrophin. All hormones being analyzed by using electrochemiluminescence methods (Cobas 411 by Roche) as a single batch, each patient was given a unique numerical identifier, which issued in data analysis. P values <0.05 were considered significant. Results: the patients' characteristics , basal serum estradiol (E2), FSH and AMH levels at day 2 of cycle and subsequent days after stimulation . As expected significant differences were observed for total dosage of FSH, peak E2 levels and duration of stimulation between short and long GnRH agonist groups. The ROC curve was used to assess the AMH values in different days (day 2, 4, 6, 8, and 10) for prediction of IVF outcomes (implantation, abortion, preganancy and live birth). All the days showed significant area under the curve (AUC) (p<0.05). However, when all the ROC curve were comapred to each others there were no significance differences bwteeen them (p>0.05) Conclusions: The present study concluded that measurement of serum AMH at any time after stimulation still predictive of the IVF outcomes which will reinforce the already known value of AMH in clinical practice.

A Simulation-Based Error Budget of the TES Method for the Design of the Spectral Configuration of the Micro-Bolometer-Based MISTIGRI Thermal Infrared Sensor

In preparation of the micro-bolometer-based MIcro Satellite for Thermal Infrared GRound surface Imaging (MISTIGRI) mission, we study the error budget of the Temperature-Emissivity Separation (TES) method using several spectral configurations that differ in channel numbers, locations, and widths. The error budget quantifies the contribution of 1) the TES underlying assumption about emissivity spectral contrast, 2) the errors on atmospheric corrections, and 3) the instrumental noise. When dealing with atmospheric corrections, we consider errors in atmospheric temperature, water vapor content, and concentrations of CO2 and O3. To that end, we design an end-to-end simulator of MISTIGRI measurements in order to simulate the radiative and biophysical quantities involved in the data processing. We conduct numerous simulations over a wide range of realistic setups that include cavity effect, i.e., radiance trapping within vegetation canopy. In the case of micro-bolometer-based sensing, the current study highlights that atmospheric and instrumental noises have similar impacts on the TES retrievals, with resulting errors twice as large as those due to the TES intrinsic assumption about spectral contrast, where the latter contributes to the TES error budget within the [0.005–0.009] interval for emissivity, and within the [0.3–0.4 K] interval for land surface temperature (LST). Also, we show that retrieval performance of surface temperature is very similar across all considered MISTIGRI spectral configurations, with RMSE variation within 0.2 K. Eventually, our study permits us to select a 4-channels spectral configuration as the most suited for the MISTIGRI instrument, notably because it enables a moderately better capture of the emissivity contrast than a 3-channels one.

Design and Analysis of Controller with Selective Harmonic Compensator for Grid Connected PV System

Harmonics produced by distributed power generation systems (DPGS) is a main power quality issue, particularly due to the number of these systems connected to the grid is always increasing. This means that, it is significant to control the harmonics caused by these inverters to limit their contrary effects on the grid power quality. This paper has proposed a new proportional current controller (P Resonant Current Controller) with selective harmonic compensator for grid connected photovoltaic (PV) systems. The proportional resonant current controller (PRCC) can have a significant effect on the quality of the current supplied to the grid by the PV inverter, and hence it is essential that the controller provides a high-quality sinusoidal output with negligible distortion to avoid generating harmonics. The effectiveness of the proposed framework has been verified using simulation results in MATLAB/Simulink.
Modified Authentication Protocol and Evaluation Tool: Kerberos and BAN Logic

In today’s world the computer network communication increases the efficiency most of the organizations. Hence threats have been increased due to these online transactions/communications. These threats necessitate the researchers to improve the existing security protocols and /or develop the new ones. Authentication Protocols are one of the same which can provide the authentication, confidentiality & integrity. For checking the authenticity of messages exchange process in authentication protocols BAN logic is used. The Kerberos encrypt the information for authentications. Many organizations use it and it has five versions and versions 4 and 5 are latest. In one of over previous paper we have generalized the ticket exchange process of version 5. In this paper to make it more authenticated some modifications are proposed to both BAN and Kerberos and we defined them as R- Kerberos & RBAN. To achieve this, we have added participant’s physical address (MAC Address) as it is unique to every network adapter and can be used as our secret key.
Bar lines and beyond - Metre tracking in digital audio

When human listeners tap their feet in time to music, they are performing beat tracking. Automatic beat tracking has been the subject much interest in the the research community, but tracking higher-level metre such as measure has received less attention. This dissertation presents Metanome, which uses an autocorrelation technique to try to determine the boundaries of measure in a musical audio signal for which beat (tactus) locations are known. It achieves a success rate of 81% for music with time signatures corresponding to metrical groupings of two, but further experimentation is required to see if it can work as effectively for other time signatures.
Take-home experiments in engineering courses: evaluation methods and lessons learned

This paper reports on the evaluation findings and the lessons learned from performing take-home laboratories in four undergraduate mechanical engineering courses at the University of Rhode Island. In this project, students were provided with a compact, low-cost kit with which they can perform an experiment at home using their own PC/laptop. A Student Survey was developed and used to collect perceptions of curricular effectiveness from the URI students on a post-course basis. In addition, pre and post quizzes were administered in the affected courses. The evaluation showed several things. First, student responses on the surveys and results of quiz grades indicated that the kits played an important role in the conceptual understanding of the course material and application of the course content to real world applications. Second, across the four mechanical engineering courses in which the kits were implemented, the majority of students consistently reported that they were comfortable working on, and with the take home kits independent of a lab or instructor. They also reported that both the software and the hardware of the take home kits were easy to set up and use. Third, one semester after the kits were first placed into service, there has been a steady increase in undergraduate Mechanical Engineering student interest in system dynamics courses as evidenced by increase in the student enrollment in three of the affected courses.
Software quality evaluation through maintenance processes

the software is always required to be developed and maintained a quality to the rapid progresses in industry, technology, economy, and other fields. Thus, software maintainability is the major activity in the software life cycle. This process bypass the cost required to develop new software product. However, software maintenance costs often total twice the original development cost in the lifetime of application software. Therefore, software maintainability is considered as one of the most important quality factor in software quality models. This study introduces a software maintenance process model that emphasizes the impact of the software quality on the maintenance and considers the quality of the modified software.
