This paper studies a software vendor’s decision to o¤er perpetual or lease-based licensing when customers are uncertain about their valuation for the software prior to adoption, and adoption requires an upfront implementation cost. First, in a discrete-time overlapping-generations model, I show that perpetual licensing can be more pro…table than lease-based licensing when consumer valuation unc...

V arious IT professionals have, at one time or another, erroneously used the terms software as a service (SaaS) and service-oriented architecture (SOA) interchangeably. At best, this faulty practice creates confusion; at its worst, it can lead to poor designs. Our goal, therefore, is to clarify the meaning of these two often used and abused terms. Briefly stated, the difference between SaaS and...

Software-as-a-Service (SaaS) is a type of cloud computing in which a tenant rents access to a shared, typically web-based application hosted by a provider. Access control for SaaS should enable the tenant to control access to data that are located at the provider based on tenant-specific access control policies. To achieve this, state-of-practice SaaS applications provide application-specific a...

As software vendors provide their software as a service (SaaS) and allow users to access the software functions via open interfaces, the innovation style has shifted from local innovation of a software user, to collective innovation of an entire system of users and software. This new innovation trend directs the innovation research to the structural and evolutionary patterns of SaaS networks, i...

There are various metaheuristic algorithms which are used to solve the Traveling Salesman problem. Ant colony optimization (ACO) is one such algorithm, which is inspired by the foraging behavior of ants. In this paper, we have proposed a modified model, entitled as Signed Adaptive Ant System (SAAS) for pheromone updation of the Ant-System; SAAS exploits the properties of Adaptive Filters. The p...

The formation of clients’satisfaction in software-as-a-service (SaaS) remains unclear. Building on the relational view and outsourcing literature, this study develops a theoretical model to explain the relationships between SaaS satisfaction, relational value, and IS capabilities. Relational values are characterized as task-based value and governance-based value. IS capabilities include IS inte...

The aim of this paper is to introduce a plug-and-play mechanism for an Internet of Things (IoT) device to instantiate a Software as a Service (SaaS) application in a private cloud, built up with OpenStack. The SaaS application is the digital avatar of a physical object connected to Internet. As a proof of concept, a Vending Machine is retrofitted and connected to Internet with and Arduino Open ...

A 61-year-old woman with multiple splanchnic arterial aneurysms (SAAs) was transferred to our hospital in a state of shock. She underwent coil embolization under the diagnosis of ruptured pancreaticoduodenal artery aneurysm. Follow-up computed tomography performed 2 weeks later showed rapid enlargement of a gastric artery aneurysm, and she underwent an additional embolization. Atherosclerotic, ...
