ROBUST SECURITY OF GSM NETWORKS BASED UPON THE CERTIFICATE-LESS AUTHENTICATION MODEL

: The cellular networks are on the rise since many years. The cellular networks have gained the millions of users every year, which means the higher order bandwidth becomes the requirement of the networks for the transmission of the data of millions of users from one region to another region. In this model, security mechanism has been proposed for the privacy protection of the GSM networks. The major GSM networks are considered in the second generation and third generations. Also the fourth generation of the GSM network is emerging rapidly and capable of handling the higher number of users on one point of time. The proposed model is defined with the certificate less cryptography which utilizes the public key based cryptography for the implementation of the extra layer of security among the network nodes. The proposed will be analyzed by using the performance measures associated with the network performance and security measures. The proposed model is expected to solve the problems associated with the existing models.

Soil‐Root Interactions and Phosphorus Nutrition of Plants

One of the major functions of plant roots is that of supplying the plant with phosphorus (P) and most other essential nutrients. In this capacity, roots provide an interface for P moving from one living system—the soil—into another living system—the plant. Phosphorus moving through the soil-root interface during the process of absorption is subject to the chemical and biological reactions occurring in this zone. These reactions, therefore, play an important role in determining P flux into the root. In this chapter, we will discuss the processes and mechanisms involved in both the soil supply of P to plant roots and absorption of P by the growing root system. These processes are interrelated and complex (Fig. 12–1). Given that a plant root is not simply a sink for P, and can alter the physical, chemical, and biological properties of the soil adjacent to it, the extent of these changes and their influence on P flux into the root are considered. Because food and fiber production are vital, the majority of the research has been conducted with agronomic species. Barber (1980) discussed some of the basic concepts presented in this chapter in the previous edition of this monograph. Much has been learned about P dynamics within the soil-root interface during the past two decades, so a significant amount of new information will be presented. For more detailed information, the reader should refer to recent reviews of soil P diffusion (Jungk and Claassen, 1997; Tinker and Nye, 2000), P uptake kinetics (Nissen, 1996; Reid, 1999), rhizosphere microbiology (Bowen and Rovira, 1999), root-induced changes in soil P availability (Hinsinger, 2001), and mechanistic modeling of P uptake (Rengel, 1993; Claassen and Steingrobe, 1999). In addition, readers often will be referred to relevant material within this monograph. We hope that the information presented in this chapter will stimulate new research and ultimately lead to more effective use of both 12

– We present the results of a survey of the liverwort species occurring in a fragment of dense montane ombrophilous forest in Parque Nacional de Boa Nova, located in a transition zone between Caatinga and Atlantic Forest in southwestern Bahia State, Brazil. A total of 126 species distributed among 41 genera and 14 families were found. Sixteen species are reported for the fi rst time from the state of Bahia, while ten species represent new records for the Northeast Region of Brazil. The family Acrobolbaceae E.A. Hodgs and the genus Dicranolejeunea (Spruce) Schiff n. are also reported for the fi rst time from Bahia. Cololejeunea winkleri (Morales & Benecker) Bernecker & Pócs, is cited for the fi rst time from the Brazilian Atlantic Forest. The results obtained in this study demonstrate the importance of Parque Nacional de Boa Nova for the conservation of bryophyte biodiversity in Brazil.
An Assessment of Social and Economic Values Associated with Australia's Tropical Rivers: a scoping report to Land and Water Australia's Tropical Rivers program

Covering an area of more than 1.3 million square kilometres, the tropical rivers region of Australia includes 55 river basins and extends across all catchments from the west side of Cape York to the Kimberley, through Queensland, the Northern Territory and Western Australia. It includes some of Australia's largest river systems, which are, by area' the Flinders, Roper, Victoria and Fitzroy Rivers and, by volume, the Nicholson and Mitchell Rivers. This report presents results of a scoping study of the social and economic values of Australia's tropical rivers and broader water resources. It identifies eight themes for research.
Uncertainty and monetary policy in good and bad times

We investigate the role played by systematic monetary policy in tackling the real effects of uncertainty shocks in U.S. recessions and expansions. We model key indicators of the business cycle with a nonlinear VAR that allows for different dynamics in busts and booms. Uncertainty shocks are identified by focusing on historical events that are associated to jumps in financial volatility. Counterfactual simulations point to a greater effectiveness of systematic monetary policy in stabilizing real activity in expansions. Differently, the ability of monetary policy to tackle the macroeconomic effects of first moment financial shocks is found to be similar between states.
Control and Powertrain Management for Multi-Autonomous Hybrid Vehicles

The need for less fuel consumption and the trend of higher level of autonomy together urge the power optimization in multihybrid autonomous vehicles. Both the multivehicle coordination control and the hybrid powertrain energy management should be optimized to maximize fuel savings. In this paper, we intend to have a computationally efficient framework to optimize them individually and then evaluate the overall control performance. The optimization is conducted in series. First is at the multivehicle system's level where the distributed locally optimal solution is given for vehicles with nonlinear dynamics. Second, the powertrain management optimization is conducted at the hybrid powertrain level. We provide an analytical formulation of the powertrain optimization for each hybrid vehicle by using Pontryagin's minimum principle (PMP). By approximating the optimal instantaneous fuel consumption rate as a polynomial of the engine speed, we can formulate the optimization problem into a set of algebraic equations, which enables the computationally efficient real-time implementation. To justify the applicability of the methodology in real-time, we give directions on numerical iterative solutions for these algebraic equations. The analysis on the stability of the method is shown through statistical analysis. Finally, further simulations are given to confirm the efficacy and the robustness of the proposed optimal approach. An off-road example is given in the simulation, although the framework developed can be applied to on-road scenario as well.
Assessment of policy-society interface to increase female participation: A study of Aerospace engineering in the Maldives

This study aims to identify and analyse the various factors leading to low female participation in Maldivian aerospace industry and discuss the policies required to improve this sector. Using a qualitative method, data from both male and female aerospace engineers were collected and content analysis was used to identify themes. The results show a range of barriers influencing Maldivian women to study and participate in aerospace engineering. How the society tended to generalise all types of engineering which resulted in several misconceptions around the aerospace industry was seen. The research discusses how to improve the education and engineering policies and its interface with the Maldivian society. This work would be of use to engineering educators, policy makers and education institutions to change their practices to increase gender equity in this area. It focusses on SDG 4, 5, 8 and 10.
Applying Unsupervised Machine Learning Algorithms to Ensure Requirements Consistency

The article is devoted to the problem of ensuring the quality of requirements for complex technical systems. The purpose of this article is to apply unsupervised machine learning techniques to test a set of requirements for consistency. It is assumed that the clustering of requirements will allow us to determine the requirements that are closest in meaning to the given one, and this may indicate a possible contradiction and require additional check of potentially conflicting requirements. The article discusses a comparison of clustering methods such as k-means, agglomerative hierarchical clustering, DBSCAN, EM-algorithm, as well as methods for converting sentences into numeric vectors TF-IDF, doc2vec, BERT. BERT and k-means showed the best result — a cluster that included only conflicting requirements.
Family Practice and Palliative Care

Introduction: The need for care and palliative care increased with the prolongation of mean life expectancy. One of the most frequently observed symptoms in palliative care is pressure ulcers. We aimed to measure the knowledge levels of caregivers serving hospitalized patients in the palliative care service and to investigate their relationship with socio-demographic characteristics, especially the knowledge levels. Methods: This study enrolled 109 people providing care to patients who received inpatient palliative care between November 1 and December 31, 2018. A questionnaire including questions about socio-demographic characteristics and knowledge about pressure ulcers was administered. The pressure ulcer status of the patients was evaluated by a physician. Results: The mean age of the caregivers was 49.49 ± 10.91 years (22-69). The mean knowledge level of the participants was 70.09 ± 18.58%. The minimum score was 0, and the maximum score was 100. It was found that 62.4% of the caregivers received information about pressure ulcers in the past, 30.3% of them didn’t receive any information about pressure ulcers, and 7.3% received partial information. Conclusion: The knowledge level of the caregivers who were informed about pressure ulcers was significantly higher than those who were not informed (p=0.005). Therefore, we think that continuous education has an essential place in preventing pressure ulcers.
Family Practice and Palliative Care

Introduction: In this study, we aimed to determine the demographic and clinical characteristics of patients with pressure ulcers who received home health care in Kutahya city and to investigate the relationship between the factors related to nutrition and pressure ulcer grades. Methods: This study is designed as a retrospective and cross-sectional. The files of 500 patients who were registered at home health services unit of Kutahya Health Sciences University Training and Research Hospital between December 2016 and May 2017 were reviewed retrospectively. Of these, sixty-three patients with pressure ulcers were included in the study. Results: In this study, 26 (41.3%) were male and 37 (58.7%) were female. The mean age of the patients with pressure ulcers was 74.41 ± 12.30 (years). 36 patients (57.1%) had cerebrovascular disease, 5 patients (7.9%) had dementia, 9 patients (14.3%) had malignancy, 8 patients (12.7%) had osteoarthritis, 4 patients 6.3%) had peripheral vascular disease, and 1 patient (1.6%) had previous traffic accident. The majority (62.1%) were neurological disease-sequenced and nursing-care group. When all the patients were examined, the region with the most pressure was the sacrum (35.3%). Hemoglobin level was found to be related to pressure ulcer grade (One-way ANOVA, p = 0.019). There was no significant relationship between other nutrition-related parameters and pressure ulcer stage. Conclusion: Patients with cerebrovascular disease constitute a significant proportion of patients receiving home care services. Low hemoglobin increases the severity of the pressure ulcer. Therefore, determining risk factors that contribute to pressure ulcer formation and efforts to prevent them should be the primary target of the home health care unit.
Overseas R&D by Multinationals in Foreign Centers of Excellence

This paper examines the determinants of overseas R&D by Swedish multinationals. Our empirical results indicate that the location of R&D abroad to a large extent is motivated by the need to adapt products and processes to conditions in the foreign markets where the firms operate. However, we also find that the MNEs tend to locate their R&D in host countries which are relatively specialized technologically in the firms' own areas. This finding may suggest that one additional motive to locating R&D abroad is to gain access to knowledge in foreign "centers of excellence" and benefit from localized spillovers.
Acute pancreatitis in pregnancy.

BACKGROUND Acute pancreatitis in pregnancy is rare. Our purpose in this study was to discuss the etiology, incidence and course of pancreatitis in pregnancy and to evaluate the maternal and perinatal outcomes. METHODS Pregnant women with pancreatitis admitted to China Medical College Hospital, Taiwan, from 1980 to 1995 were studied retrospectively. A total of 16 patients were enrolled in the study. Two patients had gallstones and hyperlipidemia; four had gallstones alone; seven had hyperlipidemia alone; one had gestational diabetes mellitus; one had hyperparathyroidism and pregnancy-induced hypertension alone; and one had Hashimoto's thyroiditis. Conservative treatment and low-fat diets were administered to the patients. RESULTS The incidence of gestational pancreatitis in this series was one in 6,790 pregnancies. The fetal outcome included eight preterm deliveries and three fetal losses. There were no maternal mortalities. The etiologies of pancreatitis were primary hyperlipidemia (56.3%) and gallstones (37.5%). All patients responded favorably to supportive therapy, and most of the symptoms subsided after delivery. CONCLUSIONS Early diagnosis and treatment is of utmost importance in the management of acute pancreatitis in pregnancy. The results of this study showed good maternal outcome following appropriate treatment. Fetal prognosis was less favorable and was most often associated with hyperlipidemia. Fetal monitoring is essential during the management of pancreatitis in pregnancy.

By means of the increasing global competition and internationalization of world markets, international expatriates assignments are more and more essential to successful worldwide development for many multinational corporations. Therefore, international expatriates are imperative to the survival of globe enterprises in the twenty-first century. Expatriates can become an important human resource to international enterprises or multinational operations. To facilitate business expatriates adjust to an overseas environment and work effectively, MNCs need to recognize the demographic factors those to affect cross-cultural adjustment. The main purpose of this study is utilizing Lee’s (2002) model to investigate the relationship among the demographic factors and cross-cultural adjustment of Taiwanese expatriates assigned to Mainland. Also, the empirical outcomes were compared between Taiwanese expatriates located in Mainland China and United States. In examining the significant degree of Taiwanese expatriates assigned to Mainland China, the instrument was a questionnaire survey conducted to this study. The variables of interest were measured using items Likert-type of questions, and those items are divided into seven categories. Data collected from 353 participants who have experience of post to Mainland China for international assignments. Descriptive statistics, ANOVA and T-test were employed to analyse data. The statistical results of this study were compared Lee’s (2002) research that associated with Taiwanese banking expatriates in United States. This thesis concludes with suggestions for both international enterprises or MNCs and individual expatriate who operate overseas journey in their normal path of business.
Technical error of measurement in anthropometry *

The anthropometrical measurements have been widely utilized to follow children’s development, in the verification of the adaptations to the physical training in the athletes’ selection, in studies of ethnic characterization, among others. The control of the precision and accuracy of the measurements will result in more reliable data. The objective of the present study was to diffuse the strategies to compute the technical error of measurement (TEM) according to Kevin Norton’s and Tim Olds methodology (2000) and to analyze the laboratory’ trainees performance. Three beginner observers (anthropometrists) of the Exercise Physiology Laboratory (Labofise) of the University of Brazil were analyzed. They accomplished measures of skin folds thickness (Cescorf, 0.1 mm) in nine different anthropometric points in 35 volunteers (25.45 ± 9.96 years). To accomplish the measures the International Society for Advancement in Kinanthropometry (ISAK) was adopted. For the TEM intraevaluator verification, the measures were accomplished in the same volunteers in two different days and, to obtain the inter-observers TEM, the measures were accomplished in a same group of volunteers, in the same day by the three evaluators. The results indicated not acceptable TEMs only for two evaluators in the intra-evaluator analysis. The other TEMs reached acceptable results. Not acceptable TEMs demonstrated the need of technical training of evaluators in order to minimize the variability verified.

This paper presents a real-world case study of optimizing waste collection in Sweden. The problem, involving approximately 17,000 garbage bins served by three bin lorries, is approached as a travelling salesman problem and solved using simulation-based optimization and an evolutionary algorithm. To improve the performance of the evolutionary algorithm, it is enhanced with a repair function that adjusts its genome values so that shorter routes are found more quickly. The algorithm is tested using two crossover operators, i.e., the order crossover and heuristic crossover, combined with different mutation rates. The results indicate that the order crossover is superior to the heuristics crossover, but that the driving force of the search process is the mutation operator combined with the repair function.

Classical (or passive) elitism mechanisms in the MOEA (Multi-objective Evolutionary Algorithm) literature have a holding/sending back structure. In this paper, an active elitism mechanism for multi-objective evolutionary algorithms is proposed. In the active elitism mechanism, a set of elite (or non-dominated) individuals is excited by genetic operators (crossover/mutation) in the archive in the hope of generating better and more diverse individuals than themselves. If a set of excited elites are any better than originals, then archive can be viewed as a place of active solution provider rather than a static storage place. The main motivation behind this approach is that elite individuals are inherently the closest individuals to the solution (of any optimization problem on hand) and exciting those individuals can likely generate more significant outcomes than a far away one. The proposed active elitism mechanism is embedded into well-known multi-objective SPEA and SPEA2 methods (named ACE_SPEA and ACE_SPEA2 respectively) and compared to the original methods using four unconstrained test problems. The active elitist versions of SPEA and SPEA2 maintain better spread and convergence properties than the original methods on all test problems. The proposed active elitism mechanism can easily be integrated into existing multi-objective evolutionary algorithms to improve their performance.

Association rules are one of the most researched areas of data mining. Finding frequent patterns is an important step in association rules mining which is very time consuming and costly. In this paper, an effective method for mining association rules in the data with the oscillatory value (up, down) is presented, such as the stock price variation in stock exchange, which, just a few numbers of the counts of itemsets are searched from the database, and the counts of the rest of itemsets are computed using the relationships that exist between these types of data. Also, the strategy of pruning is used to decrease the searching space and increase the rate of the mining process. Thus, there is no need to investigate the entire frequent patterns from the database. This takes less time to find frequent patterns. By executing the MR-Miner (an acronym for “Math Rules-Miner”) algorithm, its performance on the real stock data is analyzed and shown. Our experiments show that the MR-Miner algorithm can find association rules very efficiently in the data based on Oscillatory value type.

Semantic Segmentation of Remote Sensing Images with Multi-scale Features and Attention Mechanism

The performance of existing semantic segmentation algorithms for optical remote sensing images is often affected by the issues of real-world datasets, such as the complexity of ground object categories, the dimensional changes between different classes, and the unbalanced proportion of foreground and background. To address this problem, DRCNet, a semantic segmentation model based on attention mechanism and multi-scale fusion is proposed in this paper. The DRCNet is built upon the DeepLab v3+, which introduces a dual attention module to enhance useful features, thereby alleviating the imbalance of foreground-background labels in the datasets. Meanwhile, a residual dense atrous spatial pyramid pooling model based on residual connection is designed to address the checkerboard effect caused by continuous stacking of dilated convolutions. Furthermore, the accuracy of segmentation for different-sized targets is also improved through the cross-layer interaction of multi-scale feature maps. Extensive experimental results demonstrate that the proposed DRCNet achieves an MIoU of 70.176% and a MPA of 88.203% on the Postdam dataset, which represents improvements of 1.676% and 0.339% compared to the DeepLab v3+ model, respectively.
