Automatic Path Planning Offloading Mechanism in Edge-Enabled Environments

The utilization of edge-enabled cloud computing in unmanned aerial vehicles has facilitated advances in autonomous control by employing computationally intensive algorithms frequently related to traversal among different locations in an environment. A significant problem remains in designing an effective strategy to offload tasks from the edge to the cloud. This work focuses on creating such a strategy by employing a network evaluation method built on the mean opinion score metrics in concoction with machine learning algorithms for path length prediction to assess computational complexity and classification models to perform an offloading decision on the data provided by both network metrics and solution depth prediction. The proposed system is applied to the A* path planning algorithm, and the presented results demonstrate up to 94% accuracy in offloading decisions.
A DISCONTINUOUS FUTURE FOR NUMERICAL MODELLING IN GEOMECHANICS

Finite-element or finite-difference methods are commonly used in geomechanics to model the response of soil or rock at an engineering site. These methods assume that the material is a continuum (although known discontinuities can be included explicitly). There are two drawbacks with continuum methods. Firstly, an appropriate stress-strain law for the material may not exist, or the law may be excessively complicated with many obscure parameters. Secondly, the natural development of cracks and rupture surfaces is not well-handled by continuum approaches. It is suggested that the future trend for numerical modelling in soil and rock may consist of the replacement of continuum methods by particle methods. Assemblies of discrete particles (bonded together to represent rock, and unbonded to represent soil) capture the complicated behaviour of actual material with simple assumptions and few parameters at the micro level. Complex overall behaviour arises as an emergent property of the assembly. The application of.
An algorithm for standing phase angle reduction for power system restoration

During power system restoration, it is necessary to check the phase angle between two buses before closing circuit breakers to connect a line between them. In case of large standing phase angle (SPA) difference the synchrocheck relay does not allow closing of the breaker for this line. Therefore, this SPA has to be reduced before attempting to connect the line. In this paper a new and fast method for reducing SPA is presented. For this purpose, the standing phase angle difference between two specific buses is represented in terms of sensitivity factors associated with the change in real power injections at the buses. The proposed method will act as a direct help for reducing excessive SPA difference between two buses to an acceptable limit.
Use of quality tools to identify the causes of total broiler carcasses condemnation

The disapproval of broiler carcasses in slaughterhouses leads, directly, to losing quality and quantity of produced meat, to compromising the production line efficiency and causing processing additional costs. The carcasses can be partially or completely condemned, due to numerous causes. The identification of carcasses condemnation causes and the analyses of its factors enables to minimize losses and the improvement of the slaughter process. Thus, this research aimed to: identify the causes of total broiler carcasses condemnation, by utilization of quality tools, and elaborate an action plan that would reduce the total condemnation of broiler carcasses. The study was carried out in a slaughterhouse located in the western region of the state of Paraná. It was noted that the main cause of broiler carcasses condemnation was contamination (57.0%). The factors related with the contamination of broiler carcasses were the lack of uniformity in the weight of the broilers, the inappropriate pre slaughter fasting time, flaw in the regulation of cloaca’s extracting machine, abdomen cutter and viscera extracting machine and the poor staff training.
Sociodemographic dynamics and age trajectories of depressive symptoms among adults in mid- and later life: a cohort perspective

Abstract Objectives This study explored the age trajectories of depressive symptoms across multiple cohort groups who were in middle and late adulthood; examined sociodemographic differences in these trajectories; and investigated how relevant factors contributed to depressive symptoms trends of different cohorts. Methods Drawing on data from the 1994–2016 Health and Retirement Study (HRS), we used growth curve models to examine the age patterns of depressive symptoms, changes in sociodemographic gaps in depressive symptoms trajectories, and predictors of changes in depressive symptoms. Results In general, adults’ depressive symptoms started high in middle-adulthood, declined in young-old life, increased moderately in mid-old life, and peaked in old-old life; In detail, more nuanced cohort-specific age trajectories of depressive symptoms were observed, challenging the prevailing assumption of a common age trajectory of depressive symptoms. Later-born cohorts displayed higher levels of depressive symptoms than earlier-born cohorts at observed ages. Second, we found intra-cohort sociodemographic differences in levels of depressive symptoms, but these differences’ growth rates varied by specific factors. Regardless of the cohort group, as people age, the gender gap in depressive symptoms persisted but the partnership gap reduced. A widening educational gap across cohorts was observed, but it declined with age in some cohorts. Conclusion Results suggest more evidence for the persistent inequality and age-as-leveler hypotheses rather than the cumulative (dis-)advantage hypothesis.

Marketing Communications Model for Innovation Networks

Innovation is an increasingly relevant concept for the success of any organization, but it also represents a set of internal and external considerations, barriers and challenges to overcome. Along the concept of innovation, new paradigms emerge such as open innovation and co-creation that are simultaneously innovation modifiers and intensifiers in organizations, promoting organizational openness and stakeholder integration within the value creation process. Innovation networks composed by a multiplicity of agents in co-creative work perform as innovation mechanisms to face the increasingly complexity of products, services and markets. Technology, especially the Internet, is an enabler of all process among organizations supported by co-creative platforms for innovation. The definition of marketing communication strategies that promote motivation and involvement of all stakeholders in synergic creation and external promotion is the central aspect of this research. The implementation of the projects is performed by participative workshops with stakeholders from Madan Parque through IDEAS(R)EVOLUTION methodology and the operational model LinkUp parameterized for the project. The project is divided into the first part, the theoretical framework, and the second part where a model is developed for the marketing communication strategies that appeal to the Madan Parque case study.
Liver abscesses – from diagnosis to treatment

A liver abscess is a limited, often encysted, purulent inflammation with parenchymal necrosis that is a life-threatening complication of bacterial, fungal, protozoal and worm infections. Liver abscesses can be single or multi-ple; most of them are located in the right liver lobe. The pathogenic factor responsible for the development of abscesses can be identified by collecting the lesion’s contents or the cultures of blood, bile, sometimes urine or stool samples. Diagnosis is established by serological, imaging and microscopic tests. The treatment regimen is determined mainly by the etiological factor and the size of the lesion and includes conservative treatment and mainly percutaneous procedures. The article briefly presents the epidemiology, clinical picture and the current approach to the diagnosis and treatment of liver abscesses.

Linking Export Memory Use to Export Performance: The Moderating Role of Export Coordination and Environmental Turbulence

Export memory is one of the strategic resources which an exporting organization can harness to develop and improve its international operations (Barney 1991, Coff 1997, Kedia and Chhokar 1986, Wang and Olsen 2002). This paper examines the export performance consequences of export memory use under different internal and environmental conditions (Ibeh 2003, Kay1993, Lawrence and Lorch 1967, Robertson and Chetty 2000, Rundh 2007) . Findings of the study show that export coordination moderates the export memory use - export performance relationship, but that competitive turbulence has a direct main effect on export performance. The paper concludes with managerial implications resulting from the study.
The Relationship Between the Fear of COVID-19 in the Elderly Aged 65 Years and Over and Their Levels of Adaptation to the “New Normal”: A Cross-Sectional Study

This study was carried out to determine the relationship between the fear of COVID-19 in the elderly aged 65 years and over and their levels of adaptation to the “new normal. ” This descriptive cross-sectional study was completed with 623 elderly individuals. It was determined that the individuals who adapted well to the “new normal” had high levels of adaptation to old age, while their levels of fear of COVID-19 were slightly above average (p < 0.01). Elderly individuals have tried to adapt to the “new normal” while also experiencing fear of COVID-19. In order to minimize the fear experienced by the elderly during COVID-19, adequate support and psychological support should be provided.

The solution of a mixed boundary value problem in the theory of diffraction by a semi-infinite plane

A solution is obtained for the problem of the diffraction of a plane wave sound source by a semi-infinite half plane. One surface of the half plane has a soft (pressure release) boundary condition, and the other surface a rigid boundary condition. Two unusual features arise in this boundary value problem. The first is the edge field singularity. It is found to be more singular than that associated with either a completely rigid or a completely soft semi-infinite half plane. The second is that the normal Wiener-Hopf method (which is the standard technique to solve half plane problems) has to be modified to give the solution to the present mixed boundary value problem. The mathematical problem which is solved is an approximate model for a rigid noise barrier, one face of which is treated with an absorbing fining. It is shown that the optimum attenuation in the shadow region is obtained when the absorbing lining is on the side of the screen which makes the smallest angle to the source or the receiver from the edge.
Adaptable Packet Length for Power Hungry WSN

Wireless Sensor Networks are constrained to a set of resource constraints such as battery power, bandwidth and lifetime. Power is a very serious issue and lot of work is being done in this regard. Reduction of the MAC overhead and adoption of a dynamic packet length with data aggregation leads to power optimization in WSNs. In this paper we implement an algorithm on NS3 wherein clustering of the nodes is formed by K-means clustering algorithm. We then adopt a dynamic packet length technique to minimize the power for transmission of data from nodes to cluster heads by adopting packets with different header lengths , say a smaller MAC for packets from node to cluster head and medium sized MACs for packets from cluster head to base station. The data received from the nodes at the cluster head is aggregated into the cluster node's data. The aggregation scheme consists of doping the node's data into the parity bits of the turbo encoded cluster head's data. The power saving that can be achieved with this scheme is shown using NS3 simulations. (1-3)
Analysis of Clinical Profiles, Deformities, and Plantar Pressure Patterns in Diabetic Foot Syndrome

Diabetic foot syndrome refers to heterogeneous clinical and biomechanical profiles, which render predictive models unsatisfactory. A valuable contribution may derive from identification and descriptive analysis of well-defined subgroups of patients. Clinics, biology, function, gait analysis, and plantar pressure variables were assessed in 78 patients with diabetes. In 15 of them, the 3D architecture of the foot bones was characterized by using weight-bearing CT. Patients were grouped by diabetes type (T1, T2), presence (DN) or absence (DNN) of neuropathy, and obesity. Glycated hemoglobin (HbA1c) and plantar lesions were monitored during a 48-month follow-up. Statistical analysis showed significant differences between the groups for at least one clinical (combined neuropathy score, disease duration, HbA1c), biological (age, BMI), functional (joint mobility, foot alignment), or biomechanical (regional peak pressure, pressure-time integral, cadence, velocity) variable. Twelve patients ulcerated during follow-up (22 lesions in total), distributed in all groups but not in the DNN T2 non-obese group. These showed biomechanical alterations, not always occurring at the site of lesion, and HbA1c and neuropathy scores higher than the expected range. Three of them, who also had weight-bearing CT analysis, showed >40% of architecture parameters outside the 95%CI. Appropriate grouping and profiling of patients based on multi-instrumental clinical and biomechanical analysis may help improve prediction modelling and management of diabetic foot syndrome.
Review of object instance segmentation based on deep learning

Abstract. As a challenging task in computer vision, instance segmentation has attracted extensive attention in recent years. Able to obtain very rich and refined object information, this technology shows important application value in many fields, such as intelligent driving, medical health, and remote sensing detection. Instance segmentation technology should not only identify the positions of objects but should also accurately mark the boundary of any single instance, which can be defined as solving object detection and semantic segmentation at the same time. Our study gives a detailed introduction to the background of instance segmentation technology, its development and the common datasets in this field, and further deeply discusses key issues appearing in the development of this field, with the future development direction of instance segmentation technology proposed. Our study provides an important reference for future research on this technology
Risk Assessment Embedded with Prospect Theory for Groundwater Protection from Terror Threats

Protection of drinking water reserves has been the primary concern for governing agencies, environmental stakeholders, and the general populous worldwide. The capability of engineers and planners to incorporate risk assessment in policy-making, offers a valuable tool for implementation of sound policy regarding groundwater protection, while providing an open forum type vehicle to incorporate public inputs in priority setting for protection decisions. This paper illustrates a risk assessment methodology based on prospect theory based on prospect theory systematically analyze alternative recharge zone protection approaches and respective probabilistic impact on groundwater resources, as motivated by recent development over the recharge zone of a sole source aquifer for one of the largest metropolitan areas in the United States. Logical relationships, characterized using fault tree analysis, accurately describe pathways leading from the initial policy decision to final consequences. Comparison of these risk probabilities with limits based on revealed preference concept and prospect theory, affords decision-makers the ability to screen alternatives for acceptability.
The relationship between quality improvement and firms' productivity in Malaysia

This study attempts to examine whether quality improvement aspects have influence over a firm's productivity performance within two different settings: semiconductor and medical equipment manufacturers firms in Penang, Malaysia. To achieve this aim, six identified quality-improvement-related variables – cooperation (teamwork), participation in decision-making, quality awareness, suggestions towards improvement, voluntary work and training – are examined to see whether they lead to the improvement of productivity. The study also investigates the moderating role of the level of automation between productivity and quality. Interestingly, the study found that while quality awareness, suggestions towards improvement, voluntary work and training influence productivity, the other two variables, i.e., cooperation and participation in decision making, were found to have no influence on productivity improvement for both semiconductor an medical equipment manufacturers firms.

A Survey on Routing Protocols in Wireless Ad HOC Networks

Wireless ad-hoc networks are perform many difficult jobs for communication in the environment of decentralized infrastructure such as mobile nodes, changing network topology, without base station and access points. The Wireless nodes are forming a short-term network without requirement of any existing infrastructure. In such an environment, to forward a packet from host to destination require a mobile host. In the last Twenty years, the wireless networking society has been designed hundreds of new routing protocols targeting the various design scenarios such as messages wants to delivered in a timely manner, bandwidth and power consumption, location of the nodes and so on. Routing protocols in ad-hoc networks specify communication between routers and enable them to select routes between a source and a destination. The choice of the routes is performed by routing algorithms. This article provides an overview of different ad hoc network protocols by presenting their functionality and discussion of their respective merits and drawbacks.
