Software-Defined Cloud Computing: A Systematic Review on Latest Trends and Developments
No full textCloud computing concepts offer effective and efficient tools for addressing resource-hungry computational problems. While conventional methods, architectures, and processing techniques may limit cloud data center performance, software-defined cloud computing (SDCC) is an approach where virtualization services to all network resources in a dc are software-defined and where software-defined networking (SDN) and cloud computing go hand in hand. SDCC-related concepts change the previous state of affairs by promoting the centralized control of networking functions in a data center. A key objective of developing software-driven cloud infrastructure is that the networking hardware, software, storage, security, and network traffic management is open and interoperable. This facilitates easy installation and management of networking functions in the cloud infrastructure. Employing SDCC concepts to cloud data centers can improve resource administration challenges to a greater extent. This paper presents a survey on SDCC. We begin by introducing SDCC environments and explain its main architectural components. We identify the essential contributions of various developments to this field and discuss the implementation challenges and limitations faced in their adoption. We also explore the potential of SDCC in two domains, namely, resource orchestration and application development, as case studies of specific interest. In an attempt to anticipate the future evolution, we discuss the important research opportunities and challenges in this promising field

A Mobile Cloud-Based eHealth Scheme
No full textMobile cloud computing is an emerging field that is gaining popularity across borders at a rapid pace. Similarly, the field of health informatics is also considered as an extremely important field. This work observes the collaboration between these two fields to solve the traditional problem of extracting Electrocardiogram signals from trace reports and then performing analysis. The developed system has two front ends, the first dedicated for the user to perform the photographing of the trace report. Once the photographing is complete, mobile computing is used to extract the signal. Once the signal is extracted, it is uploaded into the server and further analysis is performed on the signal in the cloud. Once this is done, the second interface, intended for the use of the physician, can download and view the trace from the cloud. The data is securely held using a password-based authentication method. The system presented here is one of the first attempts at delivering the total solution, and after further upgrades, it will be possible to deploy the system in a commercial setting

Lack of bioactivity of three-dimensional (3D)-printed poly-є-caprolactone (PCL) scaffolds limits cell-material interactions in bone tissue engineering. This limitation can be overcome using surface-functionalization by glycosaminoglycan-like anionic polysaccharides, e.g. carboxymethyl cellulose (CMC), a plant-based carboxymethylated, unsulfated polysaccharide, and κ-carrageenan, a seaweed-derived sulfated, non-carboxymethylated polysaccharide. Sulfation of CMC and carboxymethylation of κ-carrageenan critically improve their bioactivity. This study showed for the first-time that surface-functionalization by SCMC is superior to CM-к-Car in increasing hydrophilicity and surface charge, as well as pre-osteoblast proliferation, and collagen production. However, CM-к-Car has an important advantage over SCMC in enhancing surface roughness, as well as promoting osteogenic differentiation of pre-osteoblasts. To the best of our knowledge, surface-functionalization by SCMC or CM-к-Car is a novel feasible strategy to enhance osteoblast proliferation and differentiation on biomaterials, which might improve bone regeneration and seamless biomaterial integration into the bone.</p
Biogas energy / Tasneem Abbasi, S.M. Tauseef, S.A. Abbasi.
No full textIncludes bibliographical references.Book Fair 2013.xiii, 169 p. :In recent years, the importance of biogas energy has risen manifold and has become universal. This is due to the realization that biogas capture and utilization has great potential in controlling global warming. By capturing biogas wherever it is formed, we not only tap a source of clean energy, but we also prevent the escape of methane to the atmosphere. Given that methane has 25 times greater global warming potential than CO2, methane capture through biogas energy in this manner can contribute substantially towards global warming control
A multi-objective optimization approach for disruption management in an intermodal freight transport network
No full textThe growing demand for freight transportation is leading to pay more attention to the management of intermodal freight transport network (IFTN). The optimization of IFTN management will have many benefits in terms of sustainability, reducing costs and pollution. Although many studies on the optimization of IFTN operations exist, the management of disruptions deserves a particular attention since disruptions may lead to a significant drop of performance in the entire network. In particular, seaport terminals are prone to disruptions because of their key role in connecting the land side and the sea-side operations. The availability and reliability of the entire network is directly affected by their disruptions. In this paper, a multi-objective linear programming model is developed to minimize congestion in an IFTN, which is originated from the occurrence of a disruption in a seaport terminal. The model aims to minimize cost and emissions, simultaneously. Computational results of a realistic case study, inspired by an Italian IFTN, shows the effectiveness of the developed model to improve the performance of the entire network
An unusual cause of abdominal pain due to a psoas haematoma post stroke in a patient on anticoagulation
No full textIntroduction: psoas muscle haematoma is rare, and can be spontaneous, due to trauma, anticoagulation or antiplatelet therapy or haematological disorders. We present the case of a patient with an ischaemic stroke and new atrial fibrillation, who was anticoagulated, fell and had a right sided hip fracture which was repaired, but then developed left sided abdominal | hip pain a few weeks later.Method: an 81-year-old male was admitted for a urinary tract infection and progressive right leg weakness. An MRI revealed acute ischaemia of the left corona radiata. He later suffered an unwitnessed fall, resulting in a right inter trochanteric femoral fracture, which was treated with internal fixation. Two weeks later his apxiaban had been restarted and was thought to have further urosepsis, but his white cell count and CRP did not improve despite intravenous antibiotics and there was a fall in haemoglobin.Results: a CT abdomen and pelvis was done to look for an intraabdominal collection. Somewhat surpisingly, an iliopsoas abnormality with multiple small sub-2cm rim-enhancing foci of fluid, thought to be an organised haematoma. Apixaban was stopped, he was transfused and treated with intravenous antibiotics and repeat imaging 2 weeks later revealed haematoma resorption. Antiphospholipid antibodies positive, anticardiolipin negative throught to be due to DOAC treatment.Conclusions: psoas haematoma is an unusual form of intra-abdominal haemorrhage, which in this case followed trauma and anticoagulation. Presentation is commonly with abdominal pain and bruising, but atypical symptoms can occur as in this case. Abdominopelvic imaging with CT|MRI can aid diagnosis
High-velocity impact behavior of sandwich structures with AL faces and foam cores—Experimental and numerical study
No full textIn this research, the effect of layering of the foam core of sandwich structures with aluminum face-sheets (AL-1050) and also arrangements of these layers on the ballistic resistance of the structures under high-velocity impact were investigated experimentally and numerically. Three single-layer core sandwich structures and four sandwich structures with four-layer core were considered with a total fixed volume (90 ⁎ 90 ⁎ 63 mm3). These structures were impacted by a hemispherical nose cylindrical steel projectile of 20 mm length and 8 mm diameter. The impact velocity range was chosen from 188.7 to 322.6 m/s. The results of this study revealed that, considering constant core mass and total thickness, the core layering increases the ballistic limit velocity of the sandwich structures, so that the ballistic limit velocity of the sandwich structures with four-layer core, with different arrangements of layers, compared to the single-layer core structure is 5 to 8 percent higher, on average. Also, experimental and numerical results are in good agreement. In this research, the effect of parameters such as the sandwich structure core, the thickness of the face-sheets, the projectile nose geometry, the projectile diameter and mass on the ballistic limit velocity were investigated. The study showed that the removal of the core from the sandwich structure led to a 32% reduction in ballistic limit velocity. Increasing the thickness of the back face-sheet (with the constant total thickness of the two face-sheets) increases the ballistic limit velocity by more than 6%. Compared to flat nose projectile, the ballistic limit velocity of a hemispherical nose and conical nose projectiles are respectively 9.5 and 15.6% less. Considering a constant projectile mass, with an increase of 12.5 and 25% in its diameter, the ballistic limit velocity was increased by 6.5 and 14.4%, respectively, and by decreasing the diameter by 5 and 10%, the ballistic limit velocity dropped 7.9% and 13.5%, respectively. Assuming a fixed initial kinetic energy, the increase in the mass of the projectile also reduced the ballistic limit velocity, so that by increasing the 14 and 46.1% of the projectile mass, the ballistic limit velocity was reduced by 8.5 and 18.3%, respectively
