The RICH Prefetching in Edge Caches for In-Order Delivery to Connected Cars

Content caching on the edge of 5G networks is an emerging and critical feature to quench the thirst for content of future connected cars. However, the tight packaging of 5G cells, the finite storage capacity at the edge, and the need for content availability while driving motivate the need to develop smart edge caching strategies adapted to the mobility characteristics of connected cars. In this paper, we propose a scheme called RoadsIde CacHe (RICH), which optimally caches content at edge nodes where connected vehicles require it most. In particular, our scheme is designed to ensure in-order delivery of content chunks to end users. Unlike blind popularity decisions, the probabilistic caching used by RICH accounts for the user mobility information that the system can realistically acquire. Furthermore, we provide a complete system architecture and define the protocols through which the different system entities can interact. We assess the performance of our approach against state-of-the-art solutions, under realistic mobility datasets and system scenarios. Our RICH edge caching scheme improves significantly the content availability at the caches and reduces the required backhaul bandwidth, with beneficial effects for both the end users and the network operators.
Thermal rounding of the depinning transition in ultrathin Pt/Co/Pt films

We perform a scaling analysis of the mean velocity of extended magnetic domain walls driven in ultrathin Pt/Co/Pt ferromagnetic films with perpendicular anisotropy, as a function of the applied external field for different film thicknesses. We find that the scaling of the experimental data around the thermally rounded depinning transition is consistent with the universal depinning exponents theoretically expected for elastic interfaces described by the one-dimensional quenched Edwards-Wilkinson equation. In particular, values for the depinning exponent β and thermal rounding exponent ψ are tested, and the present analysis of the experimental data is compatible with β=0.33 and ψ=0.2, in agreement with numerical simulations.
15 Experience from recreational waters

Management of recreational waters is changing rapidly to accommodate recommendations driven by World Health Organization (WHO) (WHO 2003). Parallel developments in drinking water quality management have also been evident (WHO 2004). These water quality Guidelines establish the concepts of ‘profiling’ of recreational water and ‘water safety planning’ for drinking water, both based on hazard analysis and critical control point (HACCP) principles. The parallel development of real time prediction of adverse water quality conditions to facilitate the control of public health risks through the implementation of an appropriate management system presents identical challenges and opportunities in both recreational and shellfish harvesting waters. This chapter outlines some lessons from studies designed to support implementation of the WHO approach to recreational water management and suggests key research and management questions in the risk assessment debate for both water types.
A comprehensive analysis of hadronic b → s transitions in a family non-universal Z′ model

Motivated by the latest improved measurements of B-meson decays, we make a comprehensive analysis of the impact of a family non-universal Z' boson on B-s - (B) over bar (s) mixing and two-body hadronic B-meson decays, all being characterized by the quark-level b -> s transition. Explicitly 22 decay modes and the related 52 observables are considered, and some interesting correlations between them are also carefully examined. Firstly, the allowed oases of b - s - Z' coupling parameters |B-sb(L, R)| and phi(L, R)(s) are extracted from B-s - (B) over bar (s) mixing. Then, in the 'SM limit' (i.e., no new types of Z'-induced four-quark operators arise compared to the SM case), we study the Z' effects on B -> pi K, pi K* and rho K decays. It is found that a new weak phase phi(L)(s) similar to - 90 degrees is crucial for resolving the observed 'pi K CP puzzle' and the allowed cases of the other Z' coupling parameters are also strongly restricted. Moreover, the Z' effects on (B) over bar (s) -> KK, KK* and pi(0)phi decays, being induced by the same quark-level b -> sq (q) over bar (q = u, d) transitions, are also investigated. In particular, it is found that the decay (B) over bar (s) -> pi(0)phi, once measured, would play a key role in revealing the observed 'pi K CP puzzle' and probing possible new physics hints. Finally, to check the non-universality of Z' couplings to light-quark pairs, we have studied the B -> phi K decays in detail and found that the left-handed s - s - Z' coupling is different from the d - d - Z' one, which is due to the large A(CP)(dir)(B- -> phi K-) reported by the BaBar Collaboration.
THE PENNSYLVANIA STATE UNIVERSITY SCHREYER HONORS COLLEGE DEPARTMENT OF ECONOMICS HETEROGENEITY AND THE WINNER’S CURSE

Auctions provide a unique market structure through which one can analyze consumer behavior and rational decision-making. While many variables can influence an individual’s decision on the amount and timing of a bid, there is perhaps no greater factor than one’s experience. More experienced bidders are able to strategize in order to mitigate poor results, notably the “winner’s curse. ” This strategic ability could also be the result of other individual characteristics. For example, socio-economic status can influence one’s bidding strategy. Within the context of an auction setting, this thesis intends to explore the relationship between an individual’s personal background and bidding history in response to perceived negative outcomes.
Biometric Smartcard Authentication for Fog Computing

In the IoT scenario, things at the edge can create significantly large amounts of data. Fog Computing has recently emerged as the paradigm to address the needs of edge computing in the Internet of Things (IoT) and Industrial Internet of Things (IIoT) applications. In a Fog Computing environment, much of the processing would take place closer to the edge in a router device, rather than having to be transmitted to the Fog. Authentication is an important issue for the security of fog computing since services are offered to massive-scale end users by front fog nodes.Fog computing faces new security and privacy challenges besides those inherited from cloud computing. Authentication helps to ensure and confirms a user's identity. The existing traditional password authentication does not provide enough security for the data and there have been instances when the password-based authentication has been manipulated to gain access into the data. Since the conventional methods such as passwords do not serve the purpose of data security, research worksare focused on biometric user authentication in fog computing environment. In this paper, we present biometric smartcard authentication to protect the fog computing environment.
A Directional-to-Directional (DtD) MAC Protocol for Ad hoc Networks

The use of directional antennae in ad-hoc networks has received growing attention in recent years because of the benefits including, high spatial reuse, higher antenna gains, etc. At the same time, using directional antennae introduces new challenges. For example, the problem of deafness where receiver nodes may not hear handshake messages because their antennae beams are not pointing in the direction of the sender. To address these issues, new directional MAC protocols are required. In the literature, the existing directional MAC protocols assumed that nodes can operate in both directional and omni-directional modes. However, using both directional and omnidirectional modes of operation leads to the asymmetry-in-gain problem and defeats the purpose of using directional antennae [1].
Promoting cleaner production in South East Asia: a case study of the DTI/BOI Environmental Unit

This article reviews the role of the Philippine Department of Trade and Industry/Board of Investment's Environmental Unit in promoting the adoption of cleaner production technologies and practices by Philippine industry. The activities of the Environmental Unit represent a significant shift in policy away from traditional regulatory approaches towards a cooperative, partnership approach to environmental improvement. It remains to be seen, however, whether the considerable ambitions of the Environmental Unit can be matched by the implementation of effective policy instruments. This article examines existing approaches adopted by the Environmental Unit, and uses this as a basis for proposing an expanded role. The focus is on identifying strategies which mesh with overriding policy parameters of the Department of Trade/Board of Investment, such as the desire for alternatives to conventional regulation, the requirement to promote economic growth in tandem with environmental improvement and the need to avoid large drains on the public purse. The lessons drawn have a much broader application and resonate with the challenges faced by a wide variety of agencies in developing countries in the region.
WAKE EFFECTS BEHIND A FARM OF WAVE ENERGY CONVERTERS FOR IRREGULAR LONG-CRESTED AND SHORT-CRESTED WAVES

The contribution of wave energy to the renewable energy supply is rising. To extract a considerable amount of wave power, Wave Energy Converters (WECs) are arranged in several rows or in a ’farm’. WECs in a farm are interacting (e.g. the presence of other WECs influence the operational behaviour of a single WEC) and the overall power absorption is affected. In this paper wake effects in the lee of a single WEC and multiple WECs of the overtopping type, where the water volume of overtopped waves is first captured in a basin above mean sea level and then drains back to the sea through hydro turbines, are studied using the time-dependent mild-slope equation model MILDwave. The wake behind a single WEC is investigated for long-crested and short-crested incident waves. The wake becomes wider for larger wave peak periods. An increasing directional spreading results in a faster wave regeneration and a shorter wake behind the WEC. The wake in the lee of multiple WECs is calculated for two different farm lay-outs, i.e. an aligned grid and a staggered grid, with varying lateral and longitudinal spacing. The wave power redistribution in and behind each farm lay-out is studied in detail using MILDwave. In general, the staggered grid results in the highest overall wave power absorption.
Closed-form solution of curved beam model of elastic mechanical wheel

Based on the Timoshenko curved beam theory, a novel and feasible closed-form solution was proposed to deal with the internal mechanics characteristics of mechanical elastic wheel (MEW). With the Laplace transformation and boundary conditions, the governing differential equations was reduced to a single equation in regard to the rotation angle of curved beam, so as to reveal the relationship among the radial deformation, the tangential deformation and the curved angle. Furthermore, by adopting the Frobenius theory and the Green function, six normalized solutions of equations, the general solution and the free vibration of system equations were obtained. In the end, structure mechanics and vibration modal experiments were carried out and the results show that the analytical model is applicable for the experimental results.
On the essential spectrum of the hydrogen energy and related operators

Titchmarsh determined the spectrum of the Schrδdinger energy operator associated with the hydrogen atom, i.e. the operator — Δ — 1/r. He showed, in particular, that its essential spectrum consists of the positive real axis. On the other hand, Agudo-Wolf and Birman formulated overlapping criteria for a potential, which ensured that addition of such a potential does not change the essential spectrum of — Δ. These criteria do not admit the potential 1/r and a criterion admitting it is formulated in the forthcoming work of Balslev where he also considers operators in Lp spaces. In this paper we slightly extend this Balslev criterion, in case the operator is a Schrδdinger operator. Our proofs are different, inasmuch as we capitalize on the representation of the kernel of the unperturbed resolvent. Then we make essential use of a result of Friedrichs which gives a bound for the norm of an integral operator. A criterion which ensures that the essential spectra of two self adjoint operators are equal is the following: for an appropriate complex number ζ the difference of their resolvents is compact. We shall refer to this property by saying that these operators are resolvent congruent. This property requires less and ensures less, then the one introduced independently by de Branges [18] and Birman-Krein [11] in connection with the perturbation of the continuous spectrum. It is implied by one which we called relative compactness by Gokhberg-Krei n [24] and for convenience this is shown in §1. For semi-bounded operators still another property was introduced by Birman [9] who showed that his property also implies this one. In § 1 we recall the classical notion of the essential spectrum, and formulate some general operator theoretic facts, which are used in the subsequent sections. Section 2 contains two theorems. In the first one we show, in particular, that the local square integrability of 1/r and the fact that
Evaluation of Methanol, Ethanol and Acetone extracts of four plant species as repellents against Callosobruchus maculatus (Fab.)

Methanol, ethanol and acetone extracts of leaves of four plants were evaluated for repellent activity against adult Callosobruchus maculatus using a multi-choice bio-assay apparatus. The experimental plant species studied were Ocimum gratissimum (L.), Ocimum sanctum (L.), Mentha viridis (L.), and Hyptis suaveolens (L.) in the family Lamiaceae. The extracts were applied to the food source (mung beans, 25 g) at 1.0, 5.0 and 10.0 ml concentrations and repellant activity was recorded. Observations were made after three hours for each solvent-plant extract and Percentage Repellency (PR) was determined. Among four study plant species and three solvents tested, methanol extract of M. viridis (10.0 ml) showed the strongest and highest repellent effect on C. maculatus (81%). With all three solvent extracts, the percentage repellency of the C. maculatus increased significantly with the increase of concentration producing the highest at 10.0 ml. When methanol and acetone based extracts were tested against the cowpea beetles, the highest percentage repellent activity was obtained with M. viridis followed by O. gratissimum and H. suaveolens respectively. The lowest percentage repellency was observed with O. sanctum. In contrast, ethanol-based extracts of O. gratissimum facilitated the highest percentage repellency (78%) and M. viridis produced the lowest percentage repellency (55%). Significantly high PR observed in all extracts strongly indicates the presence of repellent properties in all four plants. Solvents methanol and acetone appeared to be more effective in extracting bio-active compound/s from M. viridis whereas ethanol as a solvent seemed to be more efficient with O. gratissimum. Key Words: Callosobruchus maculatus, Percentage repellency, Solvent-plant extracts
Identifying User Requirements of Mobile Government Services in Malaysia Using Focus Group Methodch

Mobile government implementation in Malaysia is still in its very early stages – indeed a comprehensive m-Government has not been shaped yet. In this regard, we need to investigate the potential needs of users of m-Government services. In addition, there is a need to describe the factors that lead to the integration of the services provided with users’ everyday practices. In this research, we examined different groups of citizens with varying needs and practices in the available technologies. Focus groups method is used to collect data. Results show that although awareness of mobile government services is reasonably high, only a small number of Malaysians actually use mobile government services. However, citizens acknowledged that mobile government services can be useful, easy to use and convenient. Moreover, both the discussion groups and the questionnaire addressed the problems, limitations, and improvement needed in mGovernment services which include information content, information presentation, system structure, search alternatives, and navigation logic.

Evolution of electron pitch angle distributions following injection from the plasma sheet

[1] The temporal evolution of the phase space density of plasma sheet electrons (100 eV–30 keV) injected into the nightside at L = 6 during moderate geomagnetic activity is investigated using a quasi-linear diffusion formulation. Scattering in energy and pitch angle during interactions with both whistler mode chorus waves and electron cyclotron harmonic waves are included using an improved wave model recently obtained using CRRES spacecraft data. We compare our simulation results with observations from the THEMIS spacecraft and demonstrate that the formation of the observed electron pitch angle distributions is mainly due to resonant interactions with a combination of upper and lower band chorus waves. The pancake distributions at low energies (E 3 keV) are explained using the banded chorus wave structure with a power minimum at half the electron cyclotron frequency. Results of the current work can be used to model the dynamical evolution and resultant global distribution of plasma sheet electrons.
On the effectiveness of isogeny walks for extending cover attacks on elliptic curves

Cryptographic systems based on the elliptic curve discrete logarithm problem (ECDLP) are widely deployed in the world today. In order for such a system to guarantee a particular security level, the elliptic curve selected must be such that it avoids a number of well-known attacks. Beyond this, one also needs to be wary of attacks whose reach can be extended via the use of isogenies. It is an open problem as to whether there exists a field for which the isogeny walk strategy can render all elliptic curves unsuitable for cryptographic use. This thesis provides a survey of the theory of elliptic curves from a cryptographic perspective and overviews a few of the well-known algorithms for computing elliptic curve discrete logarithms. We perform some experimental verification for the assumptions used in the analysis of the isogeny walk strategy for extending Weil descent-type cover attacks, and explore its applicability to elliptic curves of cryptographic size. In particular, we demonstrate for the first time that the field F2150 is partially weak for elliptic curve cryptography.
Determination of standardized prececal protein digestibility of canola meal in British United Turkeys Big 6 at different ages using multiple linear regression procedure

Ninety six 2-week-old British United Turkeys (BUT) Big 6 were assigned to 2 groups (4 replicates of 12 birds each). One basal diet and another one in which 20% canola meal replaced the corn starch in the basal diet were prepared. At 9, 16 and 21 wk of age, four birds from each pen slaughtered for digesta collection. The last two-third segment of the intestine, between the Meckel's diverticulum and about 2 cm anterior to the ileo-ceca-colonic junction, was excised. The diets and digesta were analyzed for dry matter, crude protein, and chromic oxide content. The standardized prececal protein digestibility of canola meal was calculated using multiple linear regression procedure. The standardized prececal protein digestibility of canola meal at 21 wk of age was significantly lower as compared with that of 9 wk of age; the relative weight of digestive organs also decreased significantly with increasing age (P< 0.05). By using multiple linear regression which accounted for the endogenous nitrogen losses, we showed that standardized prececal protein digestibility was also influenced by the age. Article history:
HUMAN HEALTH RISK ASSESSMENT OF HEAVY METALS INTAKE VIA CASSAVA CONSUMPTION FROM CRUDE OIL IMPACTED SOILS WITH AND WITHOUT PALM BUNCH ASH ADDITIVE

Pollution of the Niger Delta soils with heavy metals due to crude oil spillage has posed serious threat to the ecological integrity and human well-being. The study was conducted to determine the extent of contamination of Ikot Ada Udo soil and human health risk associated with consumption of cassava from the contaminated soil. The efficacy of palm bunch ash in reclaiming the contaminated soil as presently claimed by the local farmers was also examined. The contaminated soils (with and without palm bunch additive) and cassava tubers obtained from the soils were analyzed for Fe, Pb, Mn, Cr, Cu, Zn, Ni, and Cd. Contamination factor ( CF ), enrichment factor ( EF ), and geoaccumulation index ( I geo ) were calculated to ascertain the level of contamination of the soils while transfer factor (TF ), daily intake of metal ( DIM ), health risk index ( HRI ), and target hazard quotient (THQ ) were evaluated for health risk assessment. The efficacy of palm bunch ash in reclaiming the contaminated soil was evaluated by calculating the percentage heavy metal reduction (% R ) in the contaminated soil treated with palm bunch ash. CF , EF , and I geo values suggested that the contaminated soils (with and without palm bunch additive) were highly enriched with Fe, Pb, Cu, and Cr. DIM , HRI , and THQvalues pointed to high health risk for people consuming cassava products from these soils. The calculated % R showed a positive influence of palm bunch ash on the metals concentrations. % R followed the trend: Fe>Cd>Zn>Cr>Cu>Pb>Ni.
A Survey of Radiation Hardened CMOS Techniques

The universe we live in is surrounded and filled with vast amounts of radiation[14]. As we indulge more and more into exploring our universe it becomes necessary to come up with technology that can tolerate if not combat the radiation in space. Over the past few decades a number of robotic and manned space exploration systems have been realized throughout the world. Satellites and space shuttles containing thousands of electronic circuits get flown into space to read and record the observed data. Clearly these electronic devices would not be of much use if they were intolerant to radiation in space and malfunctioned regularly. For this reason, radiation, its effects on the electronics and different methods to prevent or correct the adverse effects of radiation on electronics circuits have become a large area of research in aerospace engineering. The designing and realizing of circuits or devices which are tolerant to radiation is called as the “radiation hardening” of the circuit or device. Meaning to say that these devices or circuits are “hardened” to the effects of radiation and hence the name “Rad-hard devices”.
