Social Media Use and Happiness Among Adults 45 Years and Older

SOCIAL MEDIA USE AND HAPPINESS AMONG ADULTS 45 YEARS AND OLDER by Meghan Alyssa Young Older adults are the fastest growing group to adopt and use social media. Social media allows individuals to remain socially connected when face-to-face contact becomes difficult. Previous research shows happiness may spread through face-to-face social networks. Since older adults may experience changes in their social networks over time, examining whether happiness is also related to online networks is important to understand. The purpose of this study was to examine the relationship between the use of multiple social media sites and happiness among n=870 adults age 45 years and older. Data from the 2016 wave of the General Social Survey was used to conduct crosssectional binary logistic regression analyses. Fifty-six percent of participants used at least one social media site. Findings indicate the two predictor variables of interest (amount of time spent on the internet/web-enabled applications and number of social media sites used) had no significant relationship with happiness. Happiness was significantly related to number of children, marital status, total family income, and having a graduate degree. Future research in this area can develop new theories and explore how happiness is derived through a network by comparing an individual’s in-person and online network.

Simulation-Based Performance Evaluation of an Energy-Aware Heuristic for the Scheduling of HPC Applications in Large-Scale Distributed Systems

As the distributed resources required for the processing of High Performance Computing (HPC) applications are becoming larger in scale and computational capacity, their energy consumption has become a major concern. Therefore, there is a growing focus from both the academia and the industry on the minimization of the carbon footprint of the computational resources, especially through the efficient scheduling of the workload. In this paper, a technique is proposed for the energy-aware scheduling of bag-of-tasks applications with time constraints in a large-scale heterogeneous distributed system. Its performance is evaluated by simulation and compared with a baseline algorithm. The simulation results show that the proposed heuristic not only reduces the energy consumption of the system, but also improves its performance.
The ethical problems of death pronouncement and organ donation: A commentary on Peter Singer’s article

Abstract The article is a critical commentary on Peter Singer’s thesis that the brain death definition should be replaced by a rule outlining the conditions permitting organ harvesting from patients who are biologically alive but are no longer persons. Largely agreeing with the position, I believe it can be justified not only on the basis of utilitarian arguments, but also those based on Kantian ethics and Christianity. However, due to the lack of reliable methods diagnosing complete and irreversible loss of consciousness, we should refrain from implementing upper brain death into medical practice. Organs also should not be harvested from people in a persistent vegetative state or from anencephalic children, for similar reasons. At the same time, patients who suffered from whole-brain death should not be artificially sustained; in light of current knowledge they can be declared dead and become organ donors.
A probabilistic approach for characterizing the marking system of multiplex sequencing in ABI SOLiD platform

High-Throughput Sequencers such as Illumina and ABI SOLiD, generate large quantities of data, typically above 10 Gigabytes of text files. These platforms enable multiplex sequencing, that is, the sequencing of multiple samples in a single run, through a marking system. This requires a computational process for separation the data generated, which contains the mixture of all samples in a single output. It is necessary that the quality of the marking system is evaluated to ensure the reliability of this separation. This work proposes measures to characterize the marking system obtained from SOLiD sequencing. In fact, measures presented are proven to be sufficient to describe the sequencing and hence guide the process of filtering the data and the analysis of the sequencing protocol.
Accurate Modeling for Wideband Characterization of Nematic Liquid Crystals for Microwave Applications

Liquid crystals are attractive materials for use in millimeter-wave band communications devices due to their large birefringence and reconfigurability. However, characterizing these materials is challenging at these frequencies. This work describes the modeling tools that have been developed for the accurate analysis of the liquid crystal orientation and of the wave propagation through the inhomogeneous and anisotropic liquid crystal layer. It also shows how the modeling has been used in conjunction with experimental measurement to characterize liquid crystal materials over a wide frequency range.
On the Capacity of MIMO Cellular Networks with Macrodiversity

We consider the information theoretic limits of the uplink in a MIMO cellular network with two types of macrodiversity. In the first case, the whole network acts as a multi-access channel where every base station antenna array is part of a central receiver (global macrodiversity). In the second case, we partition the network into clusters of cooperating base stations (local macrodiversity) thereby eliminating the growth in complexity at the receiver with network size. Macrodiversity is shown to provide very significant gains in sum capacity over single cell processing schemes where co-channel interference is the dominant impairment. We also explore the rate at which the sum capacity of the local macrodiversity scheme approaches that of global macrodiversity as the cluster size increases.
COLOR DISCRIMINATION RESULTS FROM A CRT DEVICE : INFLUENCE OF LUMINANCE

In this article, we report new color discrimination ellipsoids calculated from two normal observers, using a CRT device and five values of luminance at each of the five centers recommended by the CIE in 1978 (Col Res Appl 1978;3:149–151). Our main goal was to test the weighting function for lightness adopted by the CIE94 color-difference model (CIE Publication 116, 1995). Although some of the experimental conditions employed here (CRT monitor, small size of the visual field, and controlled exposure time) did not fit those recommended by this model, our results support the weighting function for lightness proposed by CIE94. The only robust trends observed in the ellipsoids obtained were a confirmation of Weber’s law and a decrease in the area of the x, y chromaticity ellipses, when the luminance of each reference stimulus increased towards the one of the surround. © 1999 John Wiley & Sons, Inc.

A New Control strategy to Enhance LVRT for Doubly Fed Induction Generator

Nowadays renewable energy resources had became more important for dropping the green house gases. Since the renewables installed in utility grid gets increasing, stabilizing the power systems becomes a major issue. For renewables integration into the utility grid, the specific requirement should be placed by the grid operators. Among grid codes issues Low-voltage ride-through (LVRT) is a most important one. In wind power system, for certain period of time the power converters are demanded by grid codes to remain coupled with grid in the event of voltage drop. In this paper a new modified computational intelligence based control strategy is proposed to enhance the LVRT capability of grid connected doubly fed induction generators (DFIG). To support grid voltage during and after the fault, wind turbine (WT) should supply reactive power to the grid which is the world–wide requirement of grid codes. To protect the rotor side converter from grid faults a conventional crowbar-based systems were used, but this method fail to fulfill the requirement since DFIG acts as squirrel cage machine during the connection of crowbar and it absorbs reactive power from the grid. This makes to design a control system without using crowbar. In order to overcome the drawbacks mentioned above, this paper proposed the new coordinated control strategy of DFIG converters which can manage to ride-through the fault without any secondary hardware. This is achieved by using fuzzy logic controller which is tuned properly by genetic algorithms. The result will prove that our proposed method is much effective. Key-Words:Fuzzy logic control, low voltage ride through (LVRT), Doubly fed induction generator (DFIG), RSC and GSC, power systems faults.
Low-Resistivity Long-Length Horizontal Carbon Nanotube Bundles for Interconnect Applications—Part I: Process Development

Although horizontally-aligned carbon nanotube (HACNT) interconnects are the most common scenarios that have been modeled and analyzed in theoretical research, fabrication of HACNT test structures has remained an enigma until now. Through addressing several fabrication challenges, this paper reports a novel process that enables fabrication of high-density, long (over hundred microns), and thick (up to micrometer) HACNT interconnects. Furthermore, horizontal CNT-based 2-D Manhattan structure is demonstrated by properly designing the catalyst and flattening process. These structures are crucial for building angled interconnects and on-chip passive devices. In addition, to address the contact issue between metal and thick HACNT bundles, a multistep lithography combined with specifically designed metal deposition technique is performed to ensure full contact configuration. Using such a process, test structures with arrays of various sizes of HACNT bundle interconnects are fabricated. The process developed in this paper provides an important platform for future research and technology development of CNT-based interconnects and passive elements.
Contour- and Grid-Based Algorithm for Mixed Triangular-Rectangular Planar Mesh Generation

A mesh generation algorithm for the Method of Moments (MoM) is described. The algorithm, named CGSM, can mesh arbitrary planar shapes described with line segments and circular arcs into mixed triangular and rectangular cells. CGSM creates contours of the meshed shape and uses them to provide edge mesh (denser mesh near edges), creates an adaptive grid and uses it to insert axis-aligned rectangles in the interior, and flnally, triangulates the remaining area (the Delaunay condition is imposed on the triangulation). CGSM is compared to two commercial applications (Designer r and IE3D TM ) on the example of a 2-GHz hybrid ring coupler. The same simulation results are obtained. However, with CGSM, simulation time is signiflcantly reduced.
A Complexity Approach to Treatment of Tense and Agreement Deficits: A Case Study

The present case study describes a complexity approach to the treatment of tense and agreement deficits in a child (SC, age 3 years and 11 months, male) with a delay in morphosyntax. We investigate whether it is possible to elicit target treatment structures (auxiliary BE in questions) in a child who does not attempt them spontaneously. Furthermore, we ask whether such elicitation promotes accuracy in target form production and generalization to less complex forms as predicted by complexity accounts. Intervention consisted of a play-based drilled task eliciting the target structure. The intervention was effective in eliciting the intervention target, as SC demonstrated increased production of the target and decreased number of prompts required to elicit the target. SC made moderate gains in the spontaneous use of the proposed generalization structures. This preliminary case study demonstrates that a complexity approach may be feasible for treatment of morphosyntax and provides support for future treatment efficacy studies.
The impact of exposure to media coverage of the 2012 Paralympic Games on mixed physical ability interactions

The current work assessed the impact of the 2012 Paralympic Games on psychological factors operating during interactions between physically disabled and non-disabled group members. In a two-wave longitudinal design the pre- to post-Paralympic increase in exposure to Paralympic media coverage led to more positive ingroup norms about disabled people’s competence and improved intergroup contact quality among both physically disabled and non-disabled participants. Moreover, more positive norms about disabled people’s competence partially mediated the relationship between media exposure and contact quality. However, exposure to Paralympic media coverage did not appear to impact embarrassment about intergroup contact within either group. Findings are discussed in terms of the efficacy and limitations of Paralympic media coverage to improve intergroup relations in the mixed physical ability context.
Requirements elicitation and analysis: Towards the automation of software project risk management

Risk management (RM) has always been the focus of software project management studies. The abilities to monitor and control the software project risks are among the critical issues examined by various researchers. This paper discusses steps in the RM process based on Boehm model. A survey was conducted to know the perceptions of respondents on their practices of managing project risks. This paper also reports the results of the survey concerning the desired features for risk management tool (RMT). In addition, a comparison with other RM process model is also included. Requirements were gathered from domain experts and were analyzed. Based on the results, the authors proposed, designed and developed the tool to automate the Boehm's RM process.
Modeling and Analysis of a Bionic Bladder System Designed for Minitype Underwater Robots

Heaving motion is an indispensably function for underwater robots. A bionic bladder system which can realize both heaving and pitching control was designed inspired by biologic fishpsilas bladder. It was mainly composed of a cylinder and a piston. The dynamic models of the bionic bladder system for heaving and pitching motion were established and based on which a dual-velocity control system was designed. The two control channels became decoupling by setting different control cycles. Simulations with the real design parameters were performed. Results indicated that a good control performance can be achieved by the bionic bladder system with proper control parameters.
XMM-Newton reveals $\sim$100 new LMXBs in M31 from variability studies

We have conducted a survey of X-ray sources in XMM-Newton observations of M31, examining their power density spectra (PDS) and spectral energy distributions (SEDs). Our automated source detection yielded 535 good X-ray sources; to date, we have studied 225 of them. In particular, we examined the PDS because low mass X-ray binaries (LMXBs) exhibit two distinctive types of PDS. At low accretion rates, the PDS is characterised by a broken power law, with the spectral index changing from $\sim$0 to $\sim$1 at some frequency in the range $\sim$0.01–1 Hz; we refer to such PDS as Type A. At higher accretion rates, the PDS is described by a simple power law; we call these PDS Type B. Of the 225 sources studied to date, 75 exhibit Type A variability, and are almost certainly LMXBs, while 6 show Type B but not Type A, and are likely LMXBs. Of these 81 candidate LMXBs, 71 are newly identified in this survey; furthermore, they are mostly found near the centre of M31. Furthermore, most of the X-ray population in the disc are associated with the spiral arms, making them likely high mass X-ray binaries (HMXBs). In general these HMXBs do not exhibit Type A variability, while many central X-ray sources (LMXBs) in the same luminosity range do. Hence the PDS may distinguish between LMXBs and HMXBs in this luminosity range.
HSDPA in Gaussian MIMO Broadcast Channels

We compare the achievable throughput of time division multiple access multiple-input multiple output (TDMAMIMO) scheme illustrated in 3rd generation partnership project (3GPP) MIMO technical report (TR), versus the sum-rate capacity of a space-time multiple access (STMA). These schemes have been proposed to improve 3GPP high speed downlink packet access (HSDPA) channel by employing multiple antennas at both transmitter and receiver. Our comparisons are focused on the performance in multi-user environments, which is considered using TDMA which is a simpler technique than STMA (e.g., Qualcomm’s High Dare Rate (HDR) and WCDMA/HSDPA). In addition, we introduce optimal power allocation strategy for HSDPA MIMO schemes under Gaussian MIMO broadcast channels (BC) by using the similarity of multiple antenna systems and multi-user channel problems.
An Innovative Face Emotion Recognition-based Platform by using a Mobile Device as a Virtual Tour

Emotions are the base of human evolution. They help us to survive and to face up all problems of our life. Without emotions human evolution was not possible and we would be in caves. Nowadays, emotions are a very important aspect in different field not only in psychology. They are very important to understand human mind and decision-making process.Emotional tourism is an example of a new way to use emotions analysis. In this field emotions are used to create a most deep experience from the begin of a travel to each steps of the journey. They help tourism to make traveler the protagonist of his travel and not just a spectator.In this paper, we are going to show an app which predicts a travel destination based on user’s mood and facial expressions to specifics visual and auditory trigger to encounter his reactions. This app uses different technology linked together to make this solution versatile and dynamic. It implements different technology modules to perform facial and mood analysis, capturing the image, store image and show all trigger to the user. By adopting this solution is possible to easily upgrade the app and each module can be changed with no large problem adapting it to the current version of the app.
Energy Efficient D 2 D Discovery for Proximity Services in 3 GPP LTE-Advanced Networks

(D2D) communications facilitate promising solutions for service optimization and spectrum/capacity efficiency in 3rd Generation Partnership Project (3GPP) networks. A key enabler for D2D communications and proximity services is the device discovery process. Currently, many aggressive peer discovery methods discussed in 3GPP could induce high energy consumption. Therefore, a critical objective in efficient D2D proximity service deployments is how to prolong the battery life time of User Equipments (UEs), by managing discovery cycles intelligently. In this paper, D2D discovery mechanisms discussed in 3GPP are studied in terms of energy consumption aspects. In particular, we consider an efficient D2D discovery mechanism that takes advantage of the concept of proximity area, a dynamic geographical region wherein UEs activate their D2D capabilities. The mechanism enables UEs to perform D2D discovery procedures only when there is a high probability to find other UEs subscribed to the same service. The energy consumption profiles of various discovery mechanisms are evaluated using simulations and the results indicate that significant energy savings can be obtained using the considered discovery mechanism.
Sensor-based navigation algorithm for car-like robot to generate completed GVG

Sensor based exploration is a task which enables a robot to explore and map an unknown environment using sensor information. This paper we present a new algorithm that enables a car-like robot to explore an unknown planar workspace, i.e, an unknown configuration space diffeomorphic to SE(2). This paper describes the procedures that are required to implement on a car-like mobile robot, a sensor based motion planning algorithm based on the Generalized Voronoi Graph (GVG). In previous research in GVG prescribed path for a circular robot with infinite detector range. The circular robot is holonomic system, but this time GVG is used in nonholonomic system, which is the central contribution of this paper.
BOINC-MR: MapReduce in a Volunteer Environment ⋆ Short Paper

Volunteer Computing (VC) harnesses computing resources from idle machines around the world to execute independent tasks, fol- lowing a centralized master/worker model. We present BOINC-MR, a system able to run MapReduce applications on top of BOINC, the most popular VC middleware in existence. We describe BOINC-MR's architecture and evaluate its performance with a typical MapReduce application. Our results show that BOINC-MR yields a performance increase of 64 % in application turnaround time and close to 50 % reduction in bandwidth usage in the server side, when compared to the unmodified BOINC system.
VLAN over multi-hop wireless LAN system

Recently, a multi-hop wireless LAN system that APs (Access Point) are connected by ad-hoc network technology each other without the need for any cable, is introduced to expand the coverage easily. And some WISPs (Wireless Internet Service Providers) announced that they will offer a public wireless LAN service in partnership with a company providing the physical wireless infrastructure. To realize that service, the VLAN technology is very useful. So we proposed VLAN over multi-hop wireless LAN system, VLAN information exchange protocol and developed the prototype system.
Let’s Begin Again: Sierra On-Line and the Origins of the Graphical Adventure Game

The author retells the origin story of Sierra On-Line and its historic first product, the graphical adventure game Mystery House. She reviews the academic and journalistic writing that placed the story almost exclusively inside a narrative about early computer games, treating it as a saga of the competition between the graphic adventures Sierra On-Line produced and the literary games developed by companies like Infocom and dubbed interactive fiction. The author argues that such video game history proved both inaccurate and obfuscating, the she uses archival documentation and a counter-historical methodology to describe a different kind origin for Sierra On-Line and to deride the obviousness of presumptive beginnings within the discipline of game history.
Anthropogenic Aerosols, Greenhouse Gases, and the Uptake, Transport, and Storage of Excess Heat in the Climate System

The largest contributor to the planetary energy imbalance is well‐mixed greenhouse gases (GHGs), which are partially offset by poorly mixed (and thus northern midlatitude dominated) anthropogenic aerosols (AAs). To isolate the effects of GHGs and AAs, we analyze data from the CMIP5 historical (i.e., all natural and anthropogenic forcing) and single forcing (GHG‐only and AA‐only) experiments. Over the duration of the historical experiment (1861–2005) excess heat uptake at the top of the atmosphere and ocean surface occurs almost exclusively in the Southern Hemisphere, with AAs canceling the influence of GHGs in the Northern Hemisphere. This interhemispheric asymmetry in surface heat uptake is eliminated by a northward oceanic transport of excess heat, as there is little hemispheric difference in historical ocean heat storage after accounting for ocean volume. Data from the 1pctCO2 and RCP 8.5 experiments suggests that the future storage of excess heat will be skewed toward the Northern Hemisphere oceans.
