CO-SIMULATION ARCHITECTURE FOR CENTRALISED DIRECT LOAD CONTROL IN SMART GRID

The Co-Simulation in the paper aims to simulate a smart grid with its two components. The approach of a common co-simulation also provides new insights for both affected domains. In the domain of communication networks, new insights about the demands of such smart grid communication can be gathered. This concerns not only the data volume and timing questions, but also reliability issues. To investigate the behaviour of the combined electrical grid and the communication network, PSS SINCAL and OPNET simulators are combined and a direct load control algorithm is implemented and tested on German distribution network. INTRODUCTION As existing power simulators are not capable to simulate network communication protocols and traffic patterns, their application are limited to simulate smart grid. Due to aforementioned reason, designing a new simulator can be expensive [1]. However, a solution can be achieved by integrating dedicated tools in one framework. Several architectures such as EPOCHS [2], GECO [3], INSPIRE [4] have been proposed in last years. And the requirements and synchronization techniques in co-simulation can be found in [1, 5]. Regarding the application areas, a cosimulation mainly is used for time critical study (dynamic simulation) or for steady-state condition such as Demand Response (DR) or Optimization [1, 6]. In Smart Grid projects, DR is mainly divided into two categories: price based and incentive based program. [7]. Direct load control (DLC) belongs to incentive based programs. And, the goal is to reduce the stresses on a grid with shedding some part of the loads during peak hours by system operator remotely [7]. In this study, it is assumed that consumption behaviour of the costumers during peak hours can be changed by system operator remotely. Besides, it is assumed that day-ahead system condition is forecasted accurately.
An adaptive Gamma method for image under non-uniform illumination

Gamma correction is a necessary operation for a digital image before it is sent to display. Uneven illumination images have low resolution and a lot of information is covered. In order to better removal of light effects and reproduce truly plain circumstances, this paper presents a new local adaptive gamma correction method. The experiment shows this method makes the brightness distribution more uniform and proved that the method compared with other methods that have better correction results.
Has the embrace of evidence-based medicine caused palliative care tolose its soul?

Background: Recent publications have suggested that palliative care may be detracting from its primary goal of providing holistic care by focusing almost entirely upon measurable clinical and scientific parameters, and neglecting psychosocial research. This paper aims to evaluate whether palliative care has indeed lost its way. Methods: We employ the example of growing calls for the adoption of Relational Autonomy in the Singaporean end-of-life care setting, and the proffering of the Ring Theory of Personhood to explore the effects of the adoption of evidence-based approaches on palliative care. Results: Evidence-based approaches of refuting efforts to employ Relational Autonomy within Confucian-led communities highlights not only the importance of the fusion of traditional empirical and psychosocial studies, but affirms the fact that palliative care continues to espouse a holistic approach. Conclusions: Evidence seems to suggest that the embrace of evidence-based medicine does not detract from the holistic nature of palliative care.
CYBERTORT (Towards an Integrated Electronic Learning Environment for Distance Learning in Law)

This paper describes the pedagogy underpinning two conceptually related designs for web-based learning. At the heart of both versions is the desire to promote deep learning, encourage an ongoing dialogue with the materials and make the learning experience meaningful. Practical outcomes are explained with some illustrations taken from the current web pages. Those from the WebCT environment are described developmentally to demonstrate how designers can move from the simple to the quite sophisticated. Both platforms could serve the needs of distance learners and to this end they are compared with the guidelines on the quality assurance of distance learning produced by the Quality Assurance Agency for Higher Education.

Stellar Stream and Halo Structure in the Andromeda Galaxy from a Subaru/Hyper Suprime-Cam Survey

We present wide and deep photometry of the northwestern part of the halo of the Andromeda galaxy (M31) using Hyper Suprime-Cam on the Subaru Telescope. The survey covers a 9.2 deg2 field in the g, i, and NB515 bands and shows a clear red giant branch (RGB) of M31's halo stars and a pronounced red clump (RC) feature. The spatial distribution of RC stars shows a prominent stream feature, the Northwestern (NW) Stream, and a diffuse substructure in the southern part of our survey field. We estimate the distances based on the RC method and obtain = 24.63 ± 0.191 (random) ± 0.057 (systematic) and 24.29 ± 0.211 (random) ± 0.057 (systematic) mag for the NW Stream and diffuse substructure, respectively, implying that the NW Stream is located behind M31, whereas the diffuse substructure is located in front of it. We also estimate line-of-sight distances along the NW Stream and find that the southern part of the stream is ∼20 kpc closer to us relative to the northern part. The distance to the NW Stream inferred from the isochrone fitting to the color–magnitude diagram favors the RC-based distance, but the tip of the RGB (TRGB)-based distance estimated for NB515-selected RGB stars does not agree with it. The surface number density distribution of RC stars across the NW Stream is found to be approximately Gaussian with an FWHM of ∼25 arcmin (5.7 kpc), with a slight skew to the southwest side. That along the NW Stream shows a complicated structure, including variations in number density and a significant gap in the stream.
An Intrusion Tolerant CA Scheme

CA (certificate authority) is a critical component in PKI. When the private key of a CA is compromised, all the certificates issued by that CA should be revoked. Keeping the private key secret while providing service on line is very important for a CA. Rather than prevent intrusions or detect them after the fact, the project ensures that the compromise of a few system components does not compromise the private key of the CA. The private key is protected by distributing it across a few servers. The private key is never reconstructed at a single online location.
Graphane with carbon dimer defects: Robust in-gap states and a scalable two-dimensional platform for quantum computation

We study the energy level structures of the defective graphane lattice, where a carbon dimer defect is created by removing the hydrogen atoms on two nearest-neighbor carbon sites. Robust defect states emerge inside the bulk insulating gap of graphane. While for the stoichiometric half-filled system there are two doubly degenerate defect levels, there are four nondegenerate and spin-polarized in-gap defect levels in the system with one electron less than half filling. A universal set of quantum gates can be realized in the defective graphane lattice, by triggering resonant transitions among the defect states via optical pulses and \emph{ac} magnetic fields. The sizable energy separation between the occupied and the empty in-gap states enables precise control at room temperature. The spatial locality of the in-gap states implies a qubit network of extremely high areal density. Based on these results, we propose that graphane as a unique platform could be used to construct the future all-purpose quantum computers.
Characterizing the behavior of bandwidth-bound applications on torus networks

It is well known that the communication performance of parallel applications can depend heavily on the mapping of tasks or processes to physical nodes in the interconnection network. Much prior work has focused on optimizing latencybound algorithms by placing frequently communicating tasks near each other on the network. However, latency optimizations do not necessarily help bandwidth-bound applications. To optimize bandwidth, we must maximize the number of links used to transfer message packets on the network without increasing the number of messages contending for the same links. This tradeoff is not well understood. In this paper, we develop a methodology to correlate network mappings with the contention they create as well as their impact on application performance. We develop a novel metric, called plateau point, that ascribes a single value to the network counter values for an application run, and we show that this metric is correlated to communication performance in bandwidth-bound applications. This metric will enable predicting application performance without doing actual runs or simulations as long as we have a model for routing of messages through the network. We also describe the queuing strategy on Blue Gene machines and the impact of the default settings on the performance of large messages. Our insights can be applied by network designers when optimizing for bandwidth-bound applications. Our study of task mappings and trade-offs between maximizing effective bandwidth and minimizing network contention is a first step towards creating automated mappings for bandwidth-bound applications.

Spacetime equilibrium at negative temperature and the attraction of gravity

We derive the Einstein equation from the condition that every small causal diamond is a variation of a flat empty diamond with the same free conformal energy, as would be expected for a near-equilibrium state. The attractiveness of gravity hinges on the negativity of the absolute temperature of these diamonds, a property we infer from the generalized entropy.
Capital-Market Effects of Securities Regulation: Prior Conditions, Implementation, and Enforcement Revisited

While it is not clear from Christensen, Hail, and Leuz (2016), the market abuse rules they examine are the same as in Cumming, Johan, and Li (2011), with a difference in focus on the date: Christensen et al. (2016) pick the date the regulations were signed into law, while Cumming et al. (2011) pick date the date the regulations were implemented with organizational agreements and computerized surveillance. Both papers study and find the exact same effect: regulatory change improves market liquidity. We explain the relative merits of the different approaches in this paper, and identify misleading statements in prior work.

The Asymmetric Impact of Customer Information Portability on Service Competition: Evidence from the Global Wireless Industry

We study the impact of customer information portability on market competition in customer‐centric, technology‐intensive service industries. By allowing customer information to be transferrable among service providers, portability in theory may help reduce switching costs and promote competition. Yet the actual consequences are unclear. To investigate this issue, we focus on the global wireless industry, and examine the impact of mobile number portability (MNP) policy. We construct a duopoly model with heterogeneous switching costs, which predicts that the market share of the large firm will shrink after MNP, while the average price may depend on firms’ customer base composition. We test these hypotheses empirically on a panel dataset of 218 wireless operators in 52 countries over 6 years. We find relative market share gains for small firms and reductions for large firms under MNP. However, large firms can maintain higher prices than small firms. Probing deeper into customer segmentation, we find that on average, the share of contract customers increases for large firms after MNP, while it decreases for small firms. Large firms are able to retain higher‐value contract customers while small firms tend to attract lower‐value “pay‐as‐you‐go” customers. Contrary to the policy intention, large firms tend to remain dominant, and MNP is incapable of changing this. In fact, contracts become even more important after MNP, highlighting the sticky “lock‐in” effect of contracts. Our findings have broad applicability to other service industries (e.g., healthcare, financial services, and digital media), where policymakers are considering making customer information more portable in hopes of increasing competition.
Accrual-Based and Real Earnings Management: An International Comparison for Investor Protection

This paper examines the differences in accrual-based and real earnings management across countries from the perspective of investor protection. Following prior research (Leuz et al., 2003), we hypothesize that accrual-based earnings management is more constrained by strict discipline in countries with stronger investor protection. For real earnings management in countries with stronger investor protection, we have two hypotheses. One is that real earnings management is more often implemented to substitute for accrual-based earnings management. The other is that real earnings management is less often implemented, as with accrual-based earnings management. Our examination uses data from 222,513 firm-year observations drawn from 38 countries covering 1991 to 2010. The results show that managers in countries with stronger investor protection tend to engage in real earnings management instead of accrual-based earnings management. We also find that real earnings management is constrained by analyst following. Our results are not affected by the control of audit quality or the calculation method used for earnings management measures according to country and year.
RSVP Reading on a Smart Watch

Reading with Rapid Serial Visual Presentation (RSVP) has shown promise for optimizing screen space and increasing reading speed without compromising comprehension. Given the wide use of small-screen devices, the present study compared RSVP and traditional reading on three types of reading comprehension, reading speed, and subjective measures on a smart watch. Results confirm previous studies that show faster reading speed with RSVP without detracting from comprehension. Subjective data indicate that Traditional is strongly preferred to RSVP as a primary reading method. Given the optimal use of screen space, increased speed and comparable comprehension, future studies should focus on making RSVP a more comfortable format.
Re-Estimating the Effects of Stricter Standards on Trade: Endogeneity Matters

In their meta-analysis of estimates of the impact of technical barriers to trade, Li and Beghin (2012) note that studies using pesticides Maximum Residue Levels (MRLs) tend to find more trade impeding effects, but these studies do not directly address the problem of endogeneity in the standards-trade relationship. Using pesticides MRL data for 53 countries over 2005-2014, we re-examine the trade effects of stricter standards accounting fully for endogeneity using three-way fixed effects. We find that the direction of the estimated trade effects gets reversed and we discuss why endogeneity biases the estimates downwards. In another original contribution, we examine the standards-trade relationship by the direction of imposition of stricter standards for a large panel. Our results suggest that stricter standards facilitate trade, irrespective of who imposes them.
Poseidon: Hardware Support for Buffer Overflow Attacks

VAIDYANATHAN, ANURADHA Poseidon: Hardware Support for Buffer Overflow Attacks (Under the direction of Dr. Gregory T. Byrd) Stack smashing attacks were the most exploited security vulnerability in the past decade, according to CERT. Using a method called stack smashing, a malicious user overflows a buffer in the stack frame, overwriting critical stack state. The return address of the current function, which is saved in the function's stack frame, is overwritten when the buffer overflows. The new return address points to the attacker's code. So, when the function is exited, control is transferred to the attacker's code instead of back to the calling function. A common way to prevent overflow-based stack smashing is to insert bounds checking code or insert sentinel values on the stack, but this requires recompilation. We propose a hardware-based method that does not require recompilation, based on the idea that an attack of this kind produces an unexpected return address. The processor maintains a separate hardware stack, called the shadow stack, and monitors the dynamic instruction stream for subroutine calls and returns. When a call instruction is retired, its return address is pushed on the shadow stack. When a return instruction is retired, the address at the top of the shadow stack is popped and compared to the target of the return instruction. If the addresses differ, then the conventional subroutine call/return semantics have been violated. This may truly be an attack, or it may be a legitimate program construct (e.g., setjmp()/longjmp()) that also violates call/return semantics. Legitimate cases are distinguished from attacks by recording the stack pointer along with the return address at the time of a call: when a subroutine returns, the stack pointer appears consistent in the case of an attack but not in the case of setjmp()/longjmp(). There are three distinct parts to the evaluation of the usefulness and the practicality of this idea. The first part is identifying the generality of this solution. This means that we seek to answer the question: “Do we detect all forms of buffer overflow attacks without raising unnecessary false positives in the case of legal program constructs? ” The second part is the actual design details of such a stack and the amount of state that needs to be recorded to facilitate the generality described above. The third part is the actual recovery mechanism that could take the form of exceptions raised that could be further handled by the Operating System. This thesis answers the generality and design questions in entirety while laying a solid basic understanding and initial set of experiments for the recovery scheme that could be utilized.

Creating a Meaningful Learning Environment: Reflection in Leadership Education.

This article examines the use of a book discussion as an instructional tool for developing leadership exploration competency skills in university students, as it pertains to the study of women and leadership. A book discussion centered on Sheryl Sandberg’s book Lean In was held as a means to conceptualize discourse regarding leadership issues in the arena of women and leadership in a multidisciplinary campus wide symposium. In an effort to assess the effectiveness of such a program to learn about leadership issues, student commentary was collected during the discussion via an audio recording device. A qualitative exploration of the resulting commentary focused on this initiative as an effort to provide insight into the efficacy of book discussions as a best practice for facilitating the engagement of students in the exploration of leadership issues. As leadership educators seek to develop pedagogical tools that catalyze transformative learning, research regarding tools and methods by which faculty equip students to explore leadership becomes increasingly critical.
Solving Traveling Salesman Problems by an ACO-and-PSO-Based Hybrid Algorithm

A hybrid algorithm is presented to solve traveling salesman problems based on ACO(Ant Colony Optimization) and PSO(Particle Swarm Optimization). In the proposed algorithm,the PSO is used to optimize the parameters in the ant colony system to improve the performance of the ACO,which makes the parameter selection for the ACO do not depend on artificial experience or repeating trials,but rely on the self-adaptive search of the particles in the PSO.
