Using Scrum and unified modelling language to analyze and design an automatic course scheduling system

ABSTRACT This research used a case study methodology to examine large-scale software projects accomplished despite ambiguous customer requirements. This study adopted Scrum as the agile software development method and used unified modelling language (UML) diagrams to enhance design implementation documents and improve the software development process. This study presented how the case company explored a Scrum-based automatic course scheduling system for elementary and secondary schools. Through interviews, the case company incorporated customers’ requirements by using the corresponding UML diagrams, which helped the project team document the software development process and design the functions to satisfy customer demand. Then, the proposed method was introduced to the automatic elementary and secondary school course scheduling system project undertaken by the case company, verifying the feasibility of the proposed method. A few problems arose in the proposed software development process, and remedies were discussed. Software companies could use these results as a reference when implementing a large-scale software project with ambiguous customer requirements.
Automating inference, learning, and design using probabilistic programming

More by this author Imagine a world where computational simulations can be inverted as easily as running them forwards, where data can be used to refine models automatically, and where the only expertise one needs to carry out powerful statistical analysis is a basic proficiency in scientific coding. Creating such a world is the ambitious long-term aim of probabilistic programming. The bottleneck for improving the probabilistic models, or simulators, used throughout the quantitative sciences.

Living with Climate Change: Assessment of the Adaptive Capacities of Smallholders in Central Rift Valley, Ethiopia

Farms less than 2 hectares have constituted almost 90% of the total number of farms in Ethiopia. These small farms are rain fed and are vulnerable to climate change and variability extremes such as droughts. This in turn undermined the ability of smallholders’ farmers to feed themselves and the growing population. A questionnaire survey was conducted with a random sample of 355 smallholder farmers distributed in three agro-ecologies, namely, lowland, midland, and highland in central rift valley of Ethiopia (Arsi Negele district). This was supplemented with 18 focus group discussions and 30 key informant interviews. How do smallholder farmers live with climate change and variability challenges? On the basis of this question, this study has assessed the factors that determine the adaptive capacities, strategies and livelihoods of smallholders to climate change and variability; and the role of climate capacities and landscape functions for sustainable adaptation in response to climate change and variability. The results showed that even if most respondents (>95%) have the perception and intention of climate change; it was nearly 3% of them have higher adaptive capacity to adapt to climate change impacts. Adaptive capacity of smallholders and the potential impact exerted by climate change risks were negatively correlated (r = −0.134 and p < 0.02). The results showed that farmers have made some evolution in their livelihoods as an adaptation strategy. Adaptation strategies explicitly depend on adaptive capacity-human, natural, financial, social and physical resources. Indeed, the results indicated limited climate-specific and climate-relevant capacities at the local level which suggests a need to strengthen climate capacities. Moreover, it has been implicated that maintaining the landscapes, which provide landscape production functions that build the well-being and adaptive capacity of farmers, could help to sustain farmers’ livelihood and build their adaptive capacity to withstand the challenges of climate change.
Mobility-Aware Content Placement for Device-to-Device Caching Systems

User mobility has a large effect on optimal content placement in device-to-device (D2D) caching networks. Since a typical user can communicate neighboring users who stay in the D2D communication area of the typical user, the optimal content placement should be changed according to the user mobility. Under consideration of randomness of incoming and outgoing users, we formulate an optimization problem to minimize the average data load of a BS. It is proved that minimization of the average data load of a BS can be transformed to maximization of a monotonic submodular function with a matroid constraint, for which a greedy algorithm can find near-optimal solutions. Moreover, when motions of neighboring users are rapid, the optimal content placement is derived in closed-form, aided by reasonable approximation and relaxation. In the high mobility regime, the optimal content placement is shown to cache partial amounts of the most popular contents.
A Laplace transform approach to the simulation of DC‐DC converters

An approach to the simulation of pulse width modulation (PWM) direct current–direct current (DC‐DC) converters operated under continuous current mode (CCM) and discontinuous current mode (DCM) is presented. It is based on the use of the Laplace transform and of dedicated models for controlled switches and diodes. Time‐domain waveforms are obtained from network functions representing the circuit under analysis without assuming small‐signal approximation. A program implementing the proposed approach has been also developed by exploiting symbolic analysis techniques. Because of its symbolic nature, it can profitably support numerical simulators in design optimization phase. Its characteristics and potentialities are shown through examples and experimental tests.
At the center of cervical carcinogenesis: synergism between high-risk HPV and the hyperactivated YAP1

ABSTRACT Human papillomavirus (HPV) is recognized as a necessary, but insufficient cause of cervical cancer. Recent in vitro and in vivo evidence from our laboratory demonstrate that hyperactivation of yes-associated protein 1 (YAP1) is sufficient to induce cervical carcinogenesis. We found that synergism between hyperactivated YAP1 and high-risk HPV is a key driver of cervical cancer initiation and progression.
What people with normative identities believe about sex, gender and sexual orientation

ABSTRACT The present study examined the beliefs of individuals with normative identities regarding sex, gender and sexual orientation. Data were collected from 691 heterosexual cisgender women and men using an online survey. Participants indicated their agreement regarding their beliefs about the nature of sex, gender and sexual orientation along four dimensions: fixed, binary (i.e. essentialist beliefs), fluid and continuous (i.e. social constructionist beliefs). Data analyses for the present study centred on four 2 (Participant Gender Identity: Woman vs. Man) × 3 (Identity Construct: Sex vs. Gender vs. Sexual Orientation) mixed ANOVAs. Findings suggested that sex, gender and sexual orientation are understood to be distinct and that essentialist and constructionist beliefs follow reverse patterns. Heterosexual cisgender adults rated sex as the most fixed and binary, followed by gender, and then sexual orientation. Conversely, participants rated sexual orientation as the most fluid and continuous followed by gender, and sex. Men consistently rated all three constructs as more fixed and binary and less fluid and continuous than did women. Discussion focuses on the utility of investigating normative beliefs about sex, gender and sexual orientation as parallel constructs.
Growth and Yield of Inpari 29 Rice Varieties on Raised-bed and Different Depths of Sunken-bed in Saline Field

Increased productivity of rice is required to meet the increasing food demand. Utilization of marginal lands, such as saline land is one of the solutions applicable to increase rice production. The objective of this study was to determine the growth and yield of Inpari 29 rice variety planted on raised-bed and different depths of sunken-bed in saline field. This study used the Split Plot Design with two treatments. The depth as the main plot consisted of two depth levels: a depth of 50 cm and a depth of 25; and the planting area field as the subplot that consisted of two levels: raised-bed and sunken-bed. The treatment was repeated three times. The rice planted in sunken-bed showed higher growth than in raised-bed as indicated by the high content of chlorophyll a, chlorophyll b, total chlorophyll, nitrate reductase activity and plant height. The rice planted in the sunken-bed yielded higher than in raised-bed as indicated by higher harvest index and the weight of grain per clump. Rice planted in 25 cm depth showed higher nitrate reductase activity and grain weight per clump than in 50 cm depth.
Bisexual Latino Men’s Motivations for Sex

Abstract Motivations for bisexual Latino men to have sex have been often overlooked in sexuality education research. This analysis examined the associations between motivations for sex (using the AMORE questionnaire) with a sample of 148 bisexual Latino men. We found that (1) depression was positively associated with sex to relieve stress; (2) machismo was positively associated with power-related sex for stress relief, pleasure, and, nurturance motives for sex; (3) procreative motives for sex were associated with perceived stress and not associated with familismo or religiosity. We conclude by presenting implications for sexuality education and therapeutic services for bisexual Latino men.
The trachea and the lungs of the Brazilian Amazon turtle, Podocnemis expansa (Testudines, Podocnemididae): morphological and ultrastructural analysis

The respiratory system of the turtle is formed by specific organs that convey air from environment to small air sacs used for gas exchange called alveoli. In Podocnemis expansa, the trachea bifurcates into two primary extrapulmonary bronchi that, at the hilum, enters each lung of a spongy appearance, and are located just beneath the carapace. Four tissue layer structure the trachea: mucosa, submucosa, cartilage and serosa. The mucosa is lined by typical respiratory epithelium, resting on lamina propria of loose connective tissue. Just beneath, the submucosa is poorly developed and continuous to the perichondrium of the hyaline cartilage piece. The serosa is constituted by connective tissue with elastic fibers. The intrapulmonary bronchus exhibits similar trachea morphology, but the cartilage pieces are fragmented. Inside the lung, projections depart from the pulmonary wall and project into the lumen, forming cup-like chambers named alveoli. Considering the projection size and the type of the lining epithelium, they are classified as primary, secondary and tertiary trabeculae. Two types of pneumocytes lined the lateral surface of trabeculae: lining pneumocyte type I and pneumocyte type II, which is also responsible for surfactant production. The trabeculae is supported by loose connective tissue rich in blood vessels, containing collagenous fibers, scarce elastic fibers as well as smooth muscles cells. The morphological analysis revealed that the trachea and the lung of Brazilian Amazon turtle possess similarities with other chelonian species with phylogenetic proximity.
Innovative synthesis and characterization of large h-BN single crystals : From bulk to nanosheets

Au cours des dernieres decennies, en raison de sa stabilite chimique et thermique exceptionnelle associee a son caractere isolant, le nitrure de bore hexagonal sous forme de nanofeuillets (BNNSs) trouve un grand interet dans de nombreuses applications. En effet, il est serieusement envisage l’utilisation de ces nanomateriaux comme support de graphene ou pour la fabrication d’heterostructures horizontales utilisables dans le domaine de la microelectronique pour des applications de nouvelle generation. Il existe deux grandes voies de synthese de ces nanostructures 2D de h-BN, par depot chimique en phase vapeur (CVD), ou par exfoliation d’un monocristal. Dans le but de preparer des BNNS de grande qualite chimique et cristalline, notre groupe propose une nouvelle strategie de synthese en associant la voie polymere preceramique (PDC) a des techniques de frittage, par Spark Plasma Sintering (SPS) et Hot Isostatic Pressing (HIP). Premierement, le comportement thermique du precurseur preceramique, le polyborazilene (PBN) a ete etudie en conditions dynamiques in-situ. Il a ainsi ete mis en evidence, le role benefique du promoteur de cristallisation (Li3N) sur la qualite cristalline du materiau final. Cependant, une etape de frittage complementaire reste obligatoire pour parfaire la structuration cristalline du h-BN. Premierement, un procede de frittage par SPS a ete mis en œuvre. Dans cette etude, ont ete particulierement etudies l’influence de la temperature de frittage (1200-1950°C) ainsi que la teneur en promoteur de cristallisation (0-10% mass.) sur la qualite cristalline du materiau final. Apres optimisation des conditions de synthese, des pastilles de h-BN composees d’une grande quantite de plaquettes monocristallines de taille d’environ 200 μm2 ont ete obtenues. Les caracterisations de ces monocristaux attestent d'une haute qualite chimique et cristalline, meme si des impuretes, sans doutes dues a l’environnement en graphite dans le SPS, sont detectees par cathodoluminescence. Enfin, des mesures physiques montrent que les BNNSs prepares presentent une constante dielectrique interessante de 3,9, associee a une resistance dielectrique correcte de 0,53 V/nm. Afin d’augmenter encore la taille des monocristaux prepares, un second procede de frittage, par HIP, a ete etudie. Cette autre combinaison originale conduit alors a des monocristaux de h-BN significativement plus gros (jusqu’a 2000 μm de taille laterale), transparents, incolores et tres faciles a exfolier. Ainsi cette nouvelle association de la synthese de PBN par voie PDCs et du procede de ceramisation par HIP nous semble une voie des plus prometteuses pour generer de grands monocristaux de h-BN et des nanofeuillets susceptibles de supporter des heterostructures a base de graphene.
The doctor-patient relationship: Participation, compliance and satisfaction

This conceptual paper aims to contribute to the services marketing literature by investigating the doctor-patient relationship through the theoretical lens of relationship marketing and the co-creation paradigm. With a clear link between satisfaction, health outcomes and the adherence to therapeutic suggestions proposed in the literature, patient satisfaction is likely to benefit not only individual health service providers but potentially the health care system as a whole. Hence, this paper conceptualises the drivers of such satisfaction, with a particular focus on the relationship between participation, compliance and satisfaction within the medical encounter, leading to a conceptual model for future empirical research. The paper provides relevant measurements and concludes with a research agenda.
Progress in the Utilization Efficiency Improvement of Hot Carriers in Plasmon-Mediated Heterostructure Photocatalysis

The effect of plasmon-induced hot carriers (HCs) enables the possibility of applying semiconductors with wide band gaps to visible light catalysis, which becomes an emerging research field in environmental protections. Continued efforts have been made for an efficient heterostructure photocatalytic process with controllable behaviors of HCs. Recently, it has been discovered that the improvement of the utilization of HCs by band engineering is a promising strategy for an enhanced catalytic process, and relevant works have emerged for such a purpose. In this review, we give an overview of the recent progress relating to optimized methods for designing efficient photocatalysts by considering the intrinsic essence of HCs. First, the basic mechanism of the heterostructure photocatalytic process is discussed, including the formation of the Schokkty barrier and the process of photocatalysis. Then, the latest studies for improving the utilization efficiency of HCs in two aspects, the generation and extraction of HCs, are introduced. Based on this, the applications of such heterostructure photocatalysts, such as water/air treatments and organic transformations, are briefly illustrated. Finally, we conclude by discussing the remaining bottlenecks and future directions in this field.
Genome-Wide Analysis of Putative ERF and DREB GENE Families in Indica Rice (O. sativa L. subsp. Indica)

Drought is a major constraint to rice production and its stability in rain-fed and poorly irrigated environments. Identifying genomic regions influencing the yield and its response to water deficits will aid in our understanding of the genetics of drought tolerance and development of more drought tolerant cultivars. Besides drought, the other major impediment to increased crop production is salt stress. In this context, identification of drought and salt-responsive genes assumes significance. In this paper we carried out genome-wide analyses to explore putative genes encoding ethylene responsive factor (ERF) and dehydration-responsive element binding proteins (DREB) in the genome of indica rice. Reference nucleotides of well established molecular function, representing each of the protein families investigated, were chosen as query sequences for searches in the indica rice genome database. Clones having genomic sequences similar to the related genes were taken and converted to amino acid sequences. Putative sequences were subjected to PROSITE and Pfam databases and 31 signature sequences related to ERF family and 30 sequences related to DREB were obtained. Proteins showing more than 30% identity were taken and phylogenetic trees were generated for each family. The results of this sudy provide basic genomic information about new ERF and DREB gene families in indica rice.
Saturation and Σ2-transfer for ERNA

Abstract Elementary Recursive Nonstandard Analysis, in short ERNA, is a constructive system of nonstandard analysis with a PRA consistency proof, proposed around 1995 by Patrick Suppes and Richard Sommer. It is built on a previous system by Rolando Chuaqui and Patrick Suppes, which was recently reconsidered by Michal Rössler and Emil Jeřábek. A Π1-transfer principle has already been added to ERNA and the consistency of the resulting theory proved in PRA. Here, we equip ERNA with Σ2-transfer and a saturation principle, while keeping the consistency proof inside PRA. We show that the extended theory allows for generalized transfer, a basic tool of nonstandard analysis, and interprets several strong theories, like BΣ2 and IΣ2.
Joint Adaptive Modulation and Transmit Power Control on FSS-OFDM Mobile Relay System

This paper proposes an adaptive modulation (AM) and a transmit power control (TPC) on frequency symbol spreading (FSS) based orthogonal frequency division multiplexing (OFDM) relay system with considering the mobility of relay node. Wireless communications often suﬀer from large propagation loss due to shadowing and multipath fading. As a solution to this problem, relay communications, which forward data messages from a source to a destination via intermediate station(s), have been focused on. It can obtain the space diversity and expand the area coverage. In the situation where relay node has mobility, propagation channel ﬂuctuates and communication quality is deteriorated. This paper presents a whole system design of FSS-OFDM employing AM and TPC. Exploiting a good match of AM and FSS, throughput performance can be signiﬁcantly improved even in high mobility environment. In addition to this, utilizing TPC, the most suitable AM is enabled and leads to a further performance enhancement. Computer simulation veriﬁes its eﬀectiveness and reveals the proposed system is the most valuable means which realizes the ﬂexible relay node deployment.
