A heuristic algorithm for project scheduling with splitting allowed
1996
In this article, we analyze the precedence diagramming method, the only published algorithm for time-only project scheduling with activity splitting allowed. The criteria used in this method (forward and backward pass computations) for deciding when an activity has to be interrupted are shown to be invalid in some situations. We look into the causes of these failures and propose new formulae that always provide feasible solutions. The new algorithm has been tested on 240 randomly generated problems ranging up to 600 activities and 7,200 precedence relationships, resulting in an average deviation from optima of less than 1 percent.
Regioselective Hydrogenation of a 60-Carbon Nanographene Molecule toward a Circumbiphenyl Core.
2019
Regioselective peripheral hydrogenation of a nanographene molecule with 60 contiguous sp2 carbons provides unprecedented access to peralkylated circumbiphenyl (1). Conversion to the circumbiphenyl core structure was unambiguously validated by MALDI-TOF mass spectrometry, NMR, FT-IR, and Raman spectroscopy. UV–vis absorption spectra and DFT calculations demonstrated the significant change of the optoelectronic properties upon peripheral hydrogenation. Stimulated emission from 1, observed via ultrafast transient absorption measurements, indicates potential as an optical gain material.
EMBEDDING CONTEXT IN INVESTIGATIONS OF AFFECTIVE VARIABILITY: AGE DIFFERENCES IN AFFECT-HEALTH LINKS
2017
Context plays a potentially important role in explaining variability in affective experiences and yet, has often been overlooked in this line of research. The current study used data from a lifespan sample of 398 German participants ranging between 12–88 years of age (M = 40, SD = 20). Participants completed computer assisted personal interviews regarding health and well-being measures, as well as experience sampling assessments of daily affective experiences and events (e.g., uplifts). Three indices of positive affect (PA) were created: mean PA, PA reactivity to uplifts, and PA variability. In general, greater mean PA and lower PA reactivity and variability were associated with better heal…
Adaptation and Validation of the Spanish Version of the Instrument to Evaluate Nurses’ Attitudes Toward Communication With the Patient for Nursing St…
2021
Communication is essential to quality of care and patient satisfaction. It has been linked to positive patient outcomes, increased engagement, improved health outcomes and safe practices. Given these benefits and the association between attitudes and behaviours, as behaviours can be predicted by studying attitudes, assessing nursing students' attitudes toward patient communication is critical as future nursing professionals. For this purpose, the main aim of this study was to adapt and validate an instrument to measure nurses´ attitudes towards communication (ACO) for nursing students. The attitudes towards communication with patients were analyzed. Then, differences in the dimensions of th…
Viabilidad de repositorios de biomedicina y ciencias de la salud en la Comunidad Valenciana
2008
Se estudian las condiciones de autoarchivo de 3.495 trabajos publicados en 109 revistas que recogen el 50% de la producción científica de la Comunidad Valenciana en biomedicina y ciencias de la salud difundida en las bases de datos ISI (período 2000-2004). Se analiza el autoarchivado desde la perspectiva de la viabilidad de implantación de repositorios institucionales y temáticos de acceso abierto. La información se ha obtenido de la base de datos Romeo disponible en la web Sherpa. Las condiciones de autoarchivo son favorables para la implantación de repositorios institucionales ya que el 56,8% de los trabajos sería depositable inmediatamente, cifra que ascendería al 72% al considerar los d…
Plan S: challenges and opportunities in Spain
2019
Spain is one of the most active European countries in the open access (OA) movement. Although the gold route has scarcely been used, the green route has been intensively implemented through fulfilment of European and national mandates and the development of institutional policies. Plan S is becoming a disruptive element in the context of scientific communication, and Spain’s possible adherence to Plan S could imply technical challenges in journals and repositories, additional costs that are difficult to estimate, or refusal to accept the Plan on the part of researchers (based on the loss of freedom to choose the journal in which to publish). However, the implementation of Plan S in Spain wo…
Proportional and Preemption-Enabled Traffic Offloading for IP Flow Mobility: Algorithms and Performance Evaluation
2018
IP Flow Mobility (IFOM) enables a user equipment to offload data traffic at the IP flow level. Although the procedure of IFOM-based flow offloading has been specified by 3GPP, how many IP flows should be offloaded and when offloading should be performed are not defined. Consequently, IP flows may be routed to a target access network which has a strong signal strength but with backhaul congestion or insufficient access capability. In this paper, we propose two algorithms, referred to as proportional offloading (PO), and proportional and preemption-enabled offloading (PPO), respectively, for IP flow offloading in hybrid cellular and wireless local area networks. The PO algorithm decides an op…
A Metaheuristic Bandwidth Allocation Scheme for FiWi Networks Using Ant Colony Optimization
2015
Optical-wireless access networks constitute a quite attractive solution to meet the ever-increasing bandwidth requirements of end-users, offering significant benefits such as ubiquitous coverage in the wireless domain and huge bandwidth in the optical domain. However, converging optical and wireless networking technologies, with Passive Optical Networks (PONs) and 4G wireless standards, such as the Worldwide Interoperability for Microwave Access (WiMAX) and the Long Term Evolution (LTE), entails major challenges that need to be addressed. In this context, designing an efficient and fair bandwidth distribution with Quality of Service (QoS) support is a difficult task due to the interdependen…
Proxy Mobile IPv6-Based Seamless Handover
2013
A prospective next generation wireless network is expected to integrate harmoniously into an IP-based core network. It is widely anticipated that IP-layer handover is a feasible solution to global mobility. However, the performance of IP-layer handover based on basic Mobile IP (MIP) cannot support real time services very well due to long handover delay. The Internet Engineering Task Force (IETF) Network-based Localized Mobility Management (NETLMM) working group developed a network-based localized mobility management protocol called Proxy Mobile IPv6 (PMIPv6) to reduce the handoff latency of MIPv6. Moreover, PMIPv6 provides the IP with the mobility to support User Equipments (UEs) without it…
Cloud-based eHealth video encoding system for real time thermographic streaming: Performance evaluation
2017
Recent studies about the use of cloud platforms indicate that more than three-fourths of healthcare institutions apply these technologies in their daily lives. However, in most cases the cloud is based on “Infrastructure as a Service”, instead of developing new applications using the benefits that can bring us this type of technology. For these reasons, this paper shows a private cloud-based system to provide a new application based on thermographic video streaming. In this case, the cloud architecture is divided into three zones. The first zone is where the patient is under medical supervision through body temperature analysis using a global thermal camera. The second zone is the cloud its…
