The halo of M105 and its group environment as traced by planetary nebula populations. II. Using kinematics of single stars to unveil the presence of intragroup light around the Leo I galaxies NGC 3384 and M105

M105 is an early-type galaxy in the nearby Leo I group, the closest galaxy group to contain all galaxy types and therefore an excellent environment to explore the low-mass end of intra-group light (IGL) assembly. We present a new extended kinematic survey of planetary nebulae (PNe) in M105 and the surrounding 30'x30' in the Leo I group with the Planetary Nebula Spectrograph. We use PNe as kinematic tracers of the diffuse stellar light in the halo and IGL and employ Gaussian mixture models to separate contributions from the companion galaxy NGC 3384 and associate PNe with halo and IGL components around M105. We present a catalogue of 314 PNe and firmly associate 93 with NGC 3384 and 169 with M105. The PNe in M105 are further associated with its halo and the surrounding exponential envelope. We construct smooth velocity and velocity dispersion fields and calculate projected rotation, velocity dispersion, and $\lambda_R$ profiles for each component. Halo PNe exhibit declining velocity dispersion and rotation profiles, while the velocity dispersion and rotation of the exponential envelope increase notably at large radii. We identify three regimes with distinct kinematics that are linked to distinct stellar population properties: (i) the rotating core (within $1~R_\mathrm{eff}$) formed in situ and dominated by metal-rich ([M/H]~0) stars likely formed in situ, (ii) the halo from 1 to $7.5~R_\mathrm{eff}$ consisting of intermediate-metallicity stars ([M/H]>-1), either formed in situ or brought in through major mergers, and (iii) the exponential envelope reaching beyond our farthest data point at 16 $R_\mathrm{eff}$, predominately composed of metal-poor ([M/H]<-1) stars. The high velocity dispersion and moderate rotation of the latter are consistent with that measured for dwarf satellite galaxies in the Leo I group, indicating that the exponential envelope traces the transition to the IGL.
Egalisation autodidacte d'un signal modulé en fréquence

We deal with the problem of blind equalization of a linear channel in the case of a phase or frequency modulated signal. The problem of cancelling interference is also treated. This paper presents a new recursive structure based on Godard’s criterion [1] for blind equalization, which employs the strategy proposed by Macchi and al [2]. The new scheme is compared to the one of its transversal counterpart, the classical CMA, and the results indicate that recursive structure exhibits superior performances to that of its transversal counterpart in the case of multipath propagation. At last, in the presence of interference, the performances of the both schemes are equivalent.
Layered Programming Model for Resource Provisioning in Fog Computing using Yet another Fog Simulator

The huge usage of IoT devices and their deployment in multiple electronic machines need to address complex computing while processing their information from that device to any other network or cloud. Fog computing address those computing needs of IoT devices by managing the connectivity at the edge of their network by allocating resources virtually in cloud. This paper provides a perspective survey on fog computing providing features on multi-tier or distributed architecture concept of it, along with applicability of programming models and management of resource provisioning among the network of IoT devices.

An Analysis of Nontechnical Game Theory on Laboratory Sales Trainees in Saudi Arabia

The purpose of this case study was to analyze 6 months of training application in a nontechnical game theory setting. Three laboratory sales trainees were studied using training reports that logged their strategic decisions and the amount of sales they obtained from their clients. A pure strategy game theory analysis was conducted on the decisions by the sales trainees. Two types of strategies were derived from the study: (a) allocentric and (b) egocentric. The egocentric strategies yielded higher personal payoffs, while the allocentric strategies yielded higher organizational payoffs. Training intervention was withheld during the 6-month period in order to allow sales trainees to select their own strategies. The conclusions from the study indicated that if training lacks strategic alignment with organizational goals, sales trainees might select egocentric strategies that yield higher personal payoffs more often than higher company payoffs.
Search-based planning for large dynamic environments

Agents operating in the real world often have to act under the conditions where time is critical: there is a limit on the time they can afford to spend on deliberating what action to execute next. Planners used by such agents must produce the best plans they can find within the amount of time available. The strategy of always searching for an optimal plan becomes infeasible in these scenarios. Instead, we must use an anytime planner. Anytime planners operate by quickly finding a highly suboptimal plan first, and then improving it until the available time runs out. In addition to the constraints on time, world models used by planners are usually imperfect and environments are often dynamic. The execution of a plan therefore often results in unexpected outcomes. An agent then needs to update the model accordingly and re-execute a planner on the new model. A planner that has a replanning capability (a.k.a. an incremental planner) can substantially speed up each planning episode in such cases, as it tries to make use of the results of previous planning efforts in finding a new plan. Combining anytime with replanning capabilities is thus beneficial. For one, at each planning episode it allows the planner to produce a better plan within the available time: both in finding the first plan as well as in improving it, the planner can use its replanning capability to accelerate the process. In addition, the combination allows one to interleave planning and execution effectively. While the agent executes the current plan, the planner can continue improving it without having to discard all of its efforts every time the model of the world is updated. This thesis concentrates on graph-based searches. It presents an alternative view of A* search, a widely popular heuristic search in AI, and then uses this view to easily derive three versions of A* search: an anytime version, an incremental version and a version that is both anytime and incremental. Each of these algorithms is also able to provide a non-trivial bound on the suboptimality of the solution it generates. We believe that the simplicity, the existence of suboptimality bounds and the generality of the presented methods contribute to the research and development of planners well suited for systems operating in the real world.
Four Misconceptions about Charity Law in Singapore

Charity law is an area of law in Singapore of which, sadly, little is known. This lack of knowledge has also led to the proliferation of a number of misconceptions. This article looks at four misconceptions, namely the legal structure of charities, the relationship between charities and Institutions of a Public Character, the definition of ‘charitable purposes’ in Singapore and the interplay between the registration requirements and the provisions on fund-raising appeals under the Charities Act.The article seeks to debunk these misconceptions by providing a clearer understanding of the legal position of charities in Singapore. This has valuable implications for reform of charity law, which is of growing importance and interest in Singapore.
Emergency Response: Unity of Effort Through a Common Operational Picture

Abstract : This research paper will review current operational constructs in emergency response specifically focusing on incidents of national significance where multiple organizations must manage crisis, respond, and provide services as an integrated team. These organizations primarily include, but are not limited to, the Department of Homeland Security, the military both active and reserve components, and civil authorities including first responders. With a focus on improving unity of effort, the common operational picture will be explored as a means to support decision making, coordination, and integration between emergency response organizations. With a common framework for collecting and disseminating information, agencies can improve efficiency, make better use of resources, and provide a coordinated and timely response during crisis. The goal is to review the roles, responsibilities, and capabilities of emergency response organizations and identify the requirements, opportunities, and challenges in the design and implementation of a common operational picture.
Predicted photoreflectance signatures on QD selective contacts for hot carrier solar cells

The CO2 emission of our present energy transformation processes, based mainly on burning fossil fuels, is possibly the main cause of global climatic change. The photovoltaic conversion of solar energy is a clean way of producing which for sustainability should (and most probably will) become a major source of electricity. The sun is a huge resource but relatively diluted and it is reasonable to expect that only high efficiency extraction can be cost effective for mass exploitation. New concepts are neccessary such as hot carrier solar cells.
2D convolution model using (in)variant kernels for fast acoustic imaging

Acoustic imaging is an advanced technique for acoustic source localization and power reconstruction using limited measurements at microphone sensors. The acoustic imaging methods often involve in two aspects: one is to build up a forward model of acoustic power propagation which requires tremendous matrix multiplications due to large dimension of the power propagation matrix; the other is to solve an inverse problem which is usually ill-posed and time consuming. In this paper, our main contribution is to propose to use 2D convolution model for fast acoustic imaging. We find out that power propagation ma-trix seems to be a quasi-Symmetric Toeplitz Block Toeplitz (STBT) matrix in the far-field condition, so that the (in)variant convolution kernels (sizes and values) can be well derived from this STBT matrix. For method validation, we use simulated and real data from the wind tunnel S2A (France) experiment for acoustic imaging on vehicle surface.

Reference manual for the UMTRI/FHWA road profiling (PRORUT) system. Final report

The objectives of this project were to assess the capabilities that are needed in a road profilometer and develop a design tailored to minimize life costs of the system. This led to the development of a system based on the IBM PC microcomputer. With the exception of a signal conditioning unit, the system is constructed from commercial components. The software controls the measurement of road profile and rut depth, the viewing of the data, and daily checks of the hardware integrity. This document is the reference manual for the system--presently known as the PRORUT system. The manual in intended to document the software and hardware components of the system, and is of special interest to the technical staff responsible for maintenance, repair, or modification of the system when required. There are three companion reports prepared as part of the same project. One gives an overview of the project (FHWA/RD-87/042), another is the PRORUT User's manual (FHWA/RD-87/043), and the third describes the validation of the system along with other profilometers at a profilometer meeting (FHWA/RD-86/100).

The role of dynamic features in speaker verification

The thesis presents study to explore the role of dynamic features in speaker verification. Based on the theory that dynamic information should contain important speaker information, modelling the dynamics should have the potential to improve the speaker verification performance. Experiments on TD-SV using segmental hidden Markov models (SHMMs) on the YOHO database show performance improvement. However there is no significant improvement for TI-SV from experiments on the Switchboard database, using segmental GMMs. Analysis of the TD-SV results confirms that the speech dynamics modeled by SHMMs contribute more to the SV accuracy. Analysis of the TI-SV results indicates that the lack of speech dynamic information is a feature of GMM systems. It seems that the priority of the maximum likelihood training algorithm is to model stationary regions, and the role of dynamic features in GMM system, is to ensure that the classification focuses on static regions rather than to model dynamics. Study on TI-SV was carried out using conventional GMMs. Without RASTA filtering, the `delta-only' system works best. However, after RASTA filtering, the `static-plus-delta' system performs best. The results suggest that the good performance of the `delta-only' system before RASTA is mainly due to the noise robustness of the delta parameters.

Design Guidelines for Cooperative UAV-supported Services and Applications

Internet of Things (IoT) systems have advanced greatly in the past few years, especially with the support of Machine Learning (ML) and Artificial Intelligence (AI) solutions. Numerous AI-supported IoT devices are playing a significant role in providing complex and user-specific smart city services. Given the multitude of heterogeneous wireless networks, the plethora of computer and storage architectures and paradigms, and the abundance of mobile and vehicular IoT devices, true smart city experiences are only attainable through a cooperative intelligent and secure IoT framework. This article provides an extensive study on different cooperative systems and envisions a cooperative solution that supports the integration and collaboration among both centralized and distributed systems, in which intelligent AI-supported IoT devices such as smart UAVs provide support in the data collection, processing and service provisioning process. Moreover, secure and collaborative decentralized solutions such as Blockchain are considered in the service provisioning process to enable enhanced privacy and authentication features for IoT applications. As such, user-specific complex services and applications within smart city environments will be delivered and made available in a timely, secure, and efficient manner.
How Much Have They Retained? The Retention of Concepts from a Freshman Electromagnetism Course by MIT Upperclass Students

Abstract During the last four years, the introductory freshmen electromagnetism course at MIT has been taught using a studio physics format entitled TEAL—Technology Enabled Active Learning. TEAL has created a collaborative, hands-on environment where students carry out desktop experiments, submit web-based assignments, and have access to a host of visualizations and simulations that help them develop stronger intuition about electromagnetic phenomena. Pre- and posttests administered to students who took the course in the TEAL format and to those who took it in a traditional lecture-recitation format indicated that TEAL students gained significantly better conceptual understanding. This study focuses on the extent to which both groups retained conceptual understanding approximately a year after finishing the course. We also analyzed the perceptions of both research groups about how the pedagogical methods used in the electromagnetism course helped them in their learning in advanced courses. Our research has indicated that the long-term effect of the TEAL format on students' retention of concepts was more noticeable than that of the traditional learning format. The significance of this research is that it is the first of its kind to provide college students' learning outcomes in both cognitive and affective domains based on a longitudinal study. The TEAL project is supported by the d’Arbeloff Fund, the MIT/Microsoft iCampus Alliance, NSF Grant #9950380 and the MIT School of Science and Department of Physics
