Severity: a QoS-aware approach to cloud application elasticity

While a multitude of cloud vendors exist today offering flexible application hosting services, the application adaptation capabilities provided in terms of autoscaling are rather limited. In most cases, a static adaptation action is used having a fixed scaling response. In the cases that a dynamic adaptation action is provided, this is based on a single scaling variable. We propose Severity, a novel algorithmic approach aiding the adaptation of cloud applications. Based on the input of the DevOps, our approach detects situations, calculates their Severity and proposes adaptations which can lead to better application performance. Severity can be calculated for any number of application QoS attributes and any type of such attributes, whether bounded or unbounded. Evaluation with four distinct workload types and a variety of monitoring attributes shows that QoS for particular application categories is improved. The feasibility of our approach is demonstrated with a prototype implementation of an application adaptation manager, for which the source code is provided.

EVALUASI AKHIR GALUR HARAPAN KACANG PANJANG (Vigna sesquipedalis L. Fruwirth) POLONG UNGU

A Final Evaluation Of Expected Lines Of Yardlong Bean (Vigna sesquipedalis L. Fruwirth) With Purple Pods. Evaluation toward expected lines yardlong bean purple pod ability conducted to obtain lines which have superiority in yield, yiled components and other traits. Evaluation was done by analyzed adaptation and stability test. Research towards 6 lines was conducted at 6 different locations based on altitude (the middle land and low land), condition areas (rainfall and temperature) as well as the conditions of cultivation (with and without mulch application). Adaptation and stability test provides information related to lines response of environmental condition for recommended cultivation on specific or all types environment. The results showed superiority pod weight per hectare of BU 1 (9,18 t ha-1) followed by BU 6 (8,81 t ha-1) and BU 4 (6,88 t ha-1). Those lines were broadly adaptive for all types of environments. Lines that adaptive in spesific environment, BU 2 (8,03 t ha-1) produced optimal yield on marginal environment, while BU 5 (10,03 t ha-1) adaptive at productive environment. Based on lines description, all lines have superiority of purple pod colored and specifically BU 3 had highest anthocyanins content.

Debunking the Fair Use vs. Fair Dealing Myth: Have We Had Fair Use All Along?

According to conventional wisdom, a fundamental difference exists between the American fair use doctrine and the Canadian (or Commonwealth) fair dealing doctrine: while American fair use can apply potentially to any purpose, Canadian fair dealing could only apply to those purposes enumerated in the statute. Accordingly, fair dealing cannot apply to dealings for other purposes even if they would otherwise be fair. This conventional wisdom is false. When the UK Parliament codified the doctrine of fair use a century ago and enacted the fair dealing provision, it had no intention to restrict or limit its application, adaptation and adjustment by the courts. The UK Parliament (and that of Canada ten years later) sought to codify a principle, an open, flexible, and general standard, not precise rules, and had no intention to prevent its application to purposes beyond those specifically mentioned in the statute. Unfortunately, the English courts, in a series of early post-codification failed to recognize this point have sentenced fair dealing to a hundred years of stagnation. Fortunately, at the turn of the twenty-first century the Supreme Court of Canada declined to follow that restrictive path. The Canadian Parliament's decision to explicitly recognize additional purposes in 2012 and add other specific exceptions moves Canadian law in the same direction. The Court's rulings and Parliament's action have entrenched fair dealing and provided a necessary correction that allows fair dealing to resume the role it was always supposed to play. However, if conventional wisdom is correct, some uses, present or future, are still categorically excluded. This is not a recipe for progress. In a legal environment that outlaws novel ways of using, reusing and disseminating works outright, fewer new forms of expression will emerge. Fortunately, there is no serious indication that this is what Parliament intended when it legislated fair dealing, and there are very good reasons to challenge the view that it did have such intentions. This chapter, adapted from an earlier piece written in 2013, explains why and includes additional evidence to that discussed in the earlier piece. It debunks the Fair Use vs. Fair Dealing Myth and shows that an open, flexible, and general fair dealing is already here. It always has been.

Background on Context-Aware Computing Systems

This chapter is consecrated to provide background information that encompass the basic concepts of context-aware pervasive computing systems. The major challenges that researchers need to consider when conducting research in context-aware pervasive computing systems and the most interesting approaches that can be used in order to deal with these challenges are reviewed. This chapter describes also the basic design principles of context-aware pervasive systems and depicts different models for representing and reasoning upon contextual information and an overview of the most known development frameworks of context-aware systems and application adaptation is presented too. Moreover, this chapter describes the usefulness of using context-awareness in ubiquitous healthcare domain and the major challenges in using context-awareness in this domain. The well-known works that have been proposed in the field of Ubiquitous healthcare are discussed too.
