While Cloud Computing has become an important topic in research and practice in recent years and widely adopted by consumers and companies around the globe, especially German small and mediumsized enterprises (SME) are reluctant with the respect to using cloud services. Scientific literature on cloud adoption in German SMEs is still scarce, in particular with respect to the use of PaaS solution...

The modern era has seen a speedy growth in the Internet of Things (IoT). As per statistics of 2020, twenty billion devices will be connected to the Internet. This massive increase in Internet connected devices will lead to a lot of efforts to execute critical concurrent applications such fire detection, health care based system, disaster management, high energy physics, automobiles, and medical...

The banking sector is one of the best examples who create Big Data with increasing transactions per second across the globe. Each bank is administered by the DBA (Database Administrator) as a technical in charge. DBA makes an arrangement in the branch to divert query from authorized user to the appropriate data repository. The SQL core Engine accepts input stream, processes and optimized to inc...

Hox transcription factors play critical roles during early vertebrate development. Previous studies have revealed an overlapping function of Hoxa1 and Hoxb1 during specification of the rhombomeres from which neural crest cells emerge. A recent study on Hoxa1 mutant mice documented its function during cardiovascular development, however, the role of Hoxb1 is still unclear. Here we show using sin...

Multi-tenant software applications serve different organizations from a single instance and help to save development, maintenance, and administration costs. The architectural concepts of these applications and their relation to emerging platform-asa-service (PaaS) environments are still not well understood, so that it is hard for many developers to design and implement such an application. Exis...

Cloud-based offerings such as Infrastructure-as-aservice (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS), are being delivered by various vendors at highly competitive prices to encourage a paradigm shift to utility computing. To optimize the operational costs of managing an IBM Cloud-based PaaS offering, a two-pronged approach has been adopted: simplification of enterpris...

Scalability is a significant feature of cloud computing, which addresses to increase or decrease the capacities of allocated virtual resources at application, platform, database and infrastructure level on demand. We investigate scalable architecture solutions for cloud PaaS that allow services to utilize the resources dynamically and effectively without directly affecting users. We have implem...

A novel polyimide (PI)/clay hybrid nanocomposite, designated as PI (PAAS)/CM, has been developed from the poly(amic acid) salt of triethylamine and organomontmorillonite (CM) using a mixture solution of tetrahydrofuran (THF) and methanol (MeOH). For comparison, two other PI/clay hybrids derived from poly(amic acid) and CM in THF/MeOH solution and N,N9-dimethylacetamide (DMAc) solution, denoted ...

Based on the knowledge that cationic polymers with different topographical structures behave differently in gene transfection process, herein, we synthesized three biodegradable poly(amido amine)s (PAAs) with the same repeating units and molecular weights except for degree of branching: linear PAA (LPAA), low-branched PAA (LBPAA), and high-branched PAA (HBPAA). We found that LBPAA could more ef...
