An Electronic Web Based Assessment System

In keeping with the outcome-based assessment outlined by ABET? s Education Criteria 2000, the School of Engineering at the University of Bridgeport has defined fifteen general student outcomes for its computer engineering program. These outcomes form the basis of its instructional program and assessment activities. In assessing and monitoring the attainment of these outcomes, formal assessment tools such as test and quizzes as well as assignment and project reports prove to be major indicators. This study is an attempt to perform the assessment process using the Internet and its capabilities. At the heart of the assessment process lies the assurance of a quality educational experience and the commitment to continued program improvement on part of the faculty and administration. Presented in the paper is a new technique for presentation of relevant materials for accreditation under ABET criteria for Engineering program. The procourse materials from all courses offered in Fall 2002 and Spring 2003 are gathered and organized into separate course websites. Our electronic assessment (e-assessment) system (http://assesseng.bridgeport.edu/) is designed and implemented such that it streamlines program improvement and allows the assessment evaluator to browse in a logical and convenient manner starting from the program objectives and outcomes to specific course materials where they are implemented. Program constituents such as the students, faculty, industry advisory board and alumni are also involved in the process. The achievement of the program outcomes and objectives is the underlying goal of the assessment process. The process also proves to be a tool to identify areas of weaknesses in the program. In this paper, the focus is on the program outcomes and how they are achieved at the course level.
How do Customers-Employees interactions influence Organizational Change ? A Theoretical Framework

The goal of this theoretical piece of research is to conceptualize the role of customers in the process of organizational change, which has not been explored in organizational research so far. In particular, we wish to shed light on the micro-processes and interactions between customers and firms’ employees in initiating, enabling and producing organizational change. Noting the absence of the customer in organizational literature, the paper adopts a transdisciplinary perspective as it analyzes and combines academic literature on organizational change on the one hand, and on services marketing and management on the other hand, to build a conceptual model of the influence of customers on organizational change dynamics. By adopting a transdisciplinary perspective to reintegrate customers as “partial employees”, this paper is apparently the first to provide insights on how customers-employees local interactions may affect organizational change dynamics. An integrative framework based on the concept of customer participation (CP) is elaborated to explain the influence of customers-employees interactional micro-processes on organizational change. Relying on this framework, we draw three research proposals that could be further used in organizational change models to refine the role of the customer in organizational changes dynamics. We deem that the model proposed reflects the current reality of companies that increasingly involve customers in their daily activities. Thus, it can help corporate players to have a better understanding of the driving forces in change processes. However, this paper is but a first attempt to explore the role of clients in organizational change. Accordingly, an empirical study would be necessary in order to validate our proposals. The results also indicate the need for further research on the role of other external stakeholders in the production of organizational change.
Parameter identification of 1 D recurrent fractal interpolation functions with applications to imaging and signal processing

Recurrent fractal interpolation functions are very useful in modelling irregular (non-smooth) data. Two methods that use bounding volumes and one that uses the concept of box-counting dimension are introduced for the identification of the vertical scaling factors of such functions. The first two minimize the area of the symmetric difference between the bounding volumes of the data points and their transformed images, while the latter aims at achieving the same box-counting dimension between the original and the reconstructed data. Comparative results with existing methods in imaging applications are given, indicating that the proposed ones are competitive alternatives for both low and high compression ratios.
HIGH EFFICIENCY HIGH TORQUE GEARBOX FOR MULTI MEGAWATT WIND TURBINES

The gearbox in a wind turbine is essential for a availability and reliability. In order to develop its optimum design features new way of gearbox designs are proposed. Epicyclic gear drives with multiple planet gears would be technically more correct to solve this torque transmission problem. This technically demanding objective is sensibly solved by the proposed gearbox solution. The following article presents the patented new design [WO 2008/104258 A1] and determines it from a scientific standpoint.
Role of Dogs in Life Satisfaction and Stress Reduction : A Comparative Study

The objective of the study was to compare the stress levels and life satisfaction between dog owners and non-dog owners. Present study was based on assumption that dogs have a vital role in maintaining the psychological health of human beings. A sample size of 100 was decided i.e. 50 for dog owners and 50 for nondog owners. Further, a qualitative data collection via semi structured interview conducted. Participants were selected from higher socioeconomic background and varied in age from 20yrs to 30 yrs. Random stratified sampling was done. Satisfaction with life scale by Diener (1985) was used to measure life satisfaction and Perceived Stress Scale by Cohen was used to measure stress in participants. The study showed lower levels of stress and high life satisfaction in participants having dogs as compared to participants not having dogs
Formation Flying near the Libration Points in the Elliptic Restricted Three-Body Problem

Abstract In this paper, quasi-periodic and periodic reference orbits in the elliptic restricted three-body problem and control strategy to maintain these orbits are proposed. To generate reference orbits, the equations of motion are normalized by the distance between the two primary bodies. The resulting equations possess Lagrangian points of circular restricted three-body problem as stationary points. Using this fact, reference orbits in the elliptic restricted problem are generated from those of the linearized equation of the circular restricted problem. This approach permits designing and maintaining small halo-like orbits near the libration points which are more flexible for space missions than natural orbits. The total velocity changes necessary to maintain these trajectories are computed and compared to those of the circular restricted problem for the Sun-Earth system.
VENUSIAN IMPACT CRATERS

In the study of geologic processes, each of the planets will provide a limited insight of its own to a particular sequence of geologic events. This is also the case when considering impact event, formation of impact craters and impactites, and the subsequent modification and deformation of the impact crater and ejecta units. This is a limitation if the approach is concentrated to a single planet only, but – after related structures have been studied from a series of similar type planetary bodies together – it will, at its best, provide the required complementary details to our understanding of the geological process at hand.
THE ACTIVITY OF ESSENTIAL OILS OBTAINED FROM SPECIES AND INTERSPECIES HYBRIDS OF THE Mentha GENUS AGAINST SELECTED PLANT PATHOGENIC BACTERIA

Plant essential oils of six aromatic herb species and interspecies hybrids of the family Lamiaceae – chocolate mint (Mentha piperita × ‘Chocolate’), pineapple mint (Mentha suaveolens ‘Variegata’), apple mint (Mentha × rotundifolia), spearmint (Mentha spicata), orange mint (Mentha × piperita ‘Granada’) and strawberry mint (Mentha × villosa ‘Strawberry’) – were investigated for antimicrobial effects against plant pathogenic bacteria: Agrobacterium tumefaciens, Pseudomonas syringae pv. syringae and Xanthomonas arboricola pv. corylina. The screening was carried out in vitro on agar plates filled with the target organism. All essential oils screened exhibited a higher level of antibacterial activity against A. tumefaciens and X. arboricola pv. corylina than streptomycin used as a standard in all tests. The antimicrobial effect of streptomycin and five mint oils was at the same level for P. syringae pv. syringae. There were no significant differences in the influence of the chocolate mint oil on the growth inhibition of all bacteria tested. Plant essential oils from pineapple mint, apple mint, spearmint and strawberry mint showed the weakest antimicrobial activity against P. syringae pv. syringae and the strongest towards A. tumefaciens and X. arboricola pv. corylina. The essential oils from strawberry mint, pineapple mint, spearmint and apple mint had the strongest effect on A. tumefaciens, and the lowest inhibitory activity was exhibited by the chocolate mint and orange mint essential oils. X. arboricola pv. corylina was the most sensitive to the strawberry mint, pineapple mint and spearmint oils. The chocolate mint oil showed the greatest activity against P. syringae pv. syringae.
MULTICOMPONENT ALLOY POWDERS PREPARATION BY MECHANICAL ALLOYING

In the last decade, multicomponent alloys arisen as new promising family of materials. The effect of milling parameters, namely milling balls size, milling speed and time on synthesis of inequiatomic AlCoCrFeNiTi0,5 mechanically alloyed (MA) powders in planetary ball mill were studied. Alloying behaviour, morphology, size and homogeneity of powders were observed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). During MA, a supersaturated Cr based solid solution with BCC structure was formed after 24 hours of milling, with significantly reduced grain size. It was revealed, that selection of milling conditions have a great influence on milled powders properties. In general softer milling condition result in decreased particle size and homogeneity
Optical Mapping with a Precise Image Registration to Observe Late Phase 3 EAD

Newly mechanisms of abnormal automaticity named as “late phase 3 early after depolarization (EAD)” was suggested recently, but it was still not fully analyzed experimentally yet. The aim of this study was to analyze the focal activities of late phase 3 EAD and clarify ventricular fibrillation (VF) reinitiation mechanisms. Methods and Results On a pathological heart specimen, we dosed Isoproterenol and Nicorandil to isolated Langendorffperfused rabbit heart. Membrane potential (Vm) and intracellular calcium (Cai ) measurements were conducted using a simultaneous dual optical mapping system with high spatial resolution and an accurate image registration. In this research we observed the Vm and Cai 2+ wave-front propagation of postshock activity and reinitiated VF after strong electric shock against VF induced by burst pacing protocol. In addition, the location where the VF likely arises from late phase 3 EAD was identified. Conclusions Evidence of late phase 3 EAD were captured, and included: (1) focal point as origin of reinitiated VF on 2D mapping image was measured, (2) Cai 2+ upstroke was faster than Vm depolarization at focal point.

EventStacks : Integration of Event Visualizations for Physical and Social Sensor Data

This paper presents a framework for spatio-temporal event visualization that integrates multiple visualizations generated from different sensor data using stacked 3D layers. It enables us to complementarily and mutually explore data from physical sensors such as smart cards and social sensors such as Twitter to discover new events, explore reasons for them, and understand their impacts on each other. We implement an example system applying a part of the framework as the first prototype and demonstrate its possibilities by showing a case study related to a date on which two mega-scale events occurred in Tokyo.
Formation Control for Unmanned Aerial Vehicles i Formation Control for Unmanned Aerial Vehicles H nrique

The dynamic simulation of Unmanned Aerial Vehicles (UAVs) is an essential tool for the development of autonomous behaviors for these platforms. The goal of this thesis is to identify a Quadrotor’s dynamics using a black-box approach, allowing the development of a simulation platform. It is aimed to stablish not only the physical model of the quadcopter, but also to identify the stability controller and other internal processes. The first part of this thesis presents a quadrotor’s model, by defining its kinematics and its dynamics, as well as the development of control methods. The second part, describes the identification methods used, firstly the Process Models, and secondly the Gaussian Processes. In the last part of this thesis, the results of the proposed identification methods are presented, firstly in a simulation environment based on the quadrotor’s mathematical model, and afterwards applied to the real system. Finally, after analyzing the results, the simulation platform is implemented.
Helical Turbine and Fish Safety

The objective of this paper is to describe research using the Helical Turbine for hydropower with particular focus on fish safety in the presence of a spinning mechanical rotor. Two possibilities of fish mortality are discussed, namely for the case of free flow in kinetic scheme (without dam), and constrained flow (with dam). Correspondingly, the following two conclusions are formulated. Probability of fish kill by kinetic turbines in free flow approaches zero since fish can easily detect and avoid the spinning rotor. The probability of fish kill in constrained flow is also very low because peripheral, helical blades of the turbine provide sufficient open space for fish passage. The latter conclusion leads to a recommendation of using a dam with helical turbines to generate much more and less expensive power than the plain kinetic scheme can provide at similar sites. Also, an inexpensive flexible barrier instead of conventional rigid dam is discussed.

AAS 17-401 OPTICAL SENSOR FOLLOW-UP TASKING ON HIGH PRIORITY UNCORRELATED TRACK

This work proposes a methodology for tasking of electro-optical sensors to search an area of state space for a particular object. This work enables current space situational awareness programs to more efficiently follow-up on an unknown object. In particular, this work looks at searching for an unknown space object with prior knowledge in the form of a set, which can be defined via an uncorrelated track. The follow-up can occur from a different location at a different time, which often requires searching a large region of the sky. This work analyzes the divergence of a search region to inform a time optimal search method. Simulation work is included to explore the effects of sensor geometry, initial detection uncertainty, and handoff delay time on total time and feasibility of follow-up.
The Italian Lentil Genetic Resources : A Worthy Basic Tool for Breeders

The present contribution reviews the lentil landraces traditionally cultivated in Italy. Due to its position in the middle of the Mediterranean, Italy represents a good territory for drawing more general conclusions. Literature regarding archaeobotanical studies, conservation, exploitation, and risk of genetic erosion or extinction of Italian germplasm is briefly discussed. Knowledge on agronomic evaluations, on variability assessed by genetic (AFLP, ISSR, SSR) and biochemical (SDS-PAGE) markers, and on relationships among the still cultivated landraces is reported. The distinctive traits of Italian lentil germplasm are evidenced, together with data on grain composition, due to its relevance for consumers and food industry. These data are discussed on the grounds of the necessity of adequate actions aimed at safeguarding these precious genetic resources. Three case studies are analysed in depth. The potential of lentil germplasm for breeding programmes aimed at the selection of ideotypes well adapted to Italian and Mediterranean environments are also discussed. _____________________________________________________________________________________________________________
On a characterisation of the finite twisted triality hexagons using one classical ideal Cayley subhexagon

Let ∆ be a generalized hexagon of order (q, q), for some prime power q not divisible by 3. Suppose that ∆ contains a subhexagon Γ of order (q, q) isomorphic to a split Cayley hexagon (associated to Dickson’s group G2(q)), and suppose that every axial elation (long root elation) in Γ is induced by Aut(∆)Γ. Then we show that ∆ is isomorphic to the twisted triality hexagon T(q, q) associated to the group D4(q).
On Privacy-Preserving Cloud Auction Conference

Due to perceived fairness and allocation efficiency, cloud auctions for resource allocation and pricing have recently attracted significant attention. As an important economic property, truthfulness makes bidders reveal their true valuations for cloud resources to maximize their utilities. However, disclosure of one’s true value causes numerous security vulnerabilities. Therefore, privacy-preserving cloud auctions are called for to prevent such information leakage. In this paper, we demonstrate how to perform privacy-preserving auctions in clouds that do not leak any information other than the auction results to anyone. Specifically, we design a privacy-preserving cloud auction framework that addresses the challenges posed by the cloud auction context by leveraging the techniques in garbled circuits and homomorphic encryption. As foundations of our privacypreserving cloud auction framework, we develop data-oblivious cloud auction algorithm and basic operations (e.g., comparison, swapping etc.), such that the execution path does not depend on the input. In practical systems with a large number of users and constrained resources, we develop an improved version with a computational complexity of O(n log n) in the number of bidders n. We further fully implement our framework and theoretically and experimentally show that it preserves privacy by incurring only limited computation and communication overhead.
L ONG GAPS IN MULTIVARIATE SPATIO-TEMPORAL DATA : AN APPROACH BASED ON F UNCTIONAL D ATA A NALYSIS

The main aim of this paper is to perform Functional Principal Component Analysis (FPCA) taking into account spatio-temporal correlation structures, in order to fill in missing values in spatio-temporal multivariate data set.A spatial and a spatio-temporal variant of the classical temporal FPCA is considered; in other words, FPCA is carried out after modeling data with respect to more than one dimension: space (long, lat) or space+time. Moreover, multidimensional FPCA is extended to multivariate context (more than one variable). Information on spatial or spatiotemporal structures are efficiently extracted by applying Generalized Additive Models (GAMs). Both simulation studies and some performance indicators are used to validate the proposed procedure, showing that, especially in presence of long gaps, spatio-temporal FPCA provides a better reconstruction than spatial FPCA.
