Lambda Calculus in Core Aldwych

Core Aldwych is a simple model for concurrent computation, involving the concept of agents which communicate through shared variables. Each variable will have exactly one agent that can write to it, and its value can never be changed once written, but a value can contain further variables which are written to later. A key aspect is that the reader of a value may become the writer of variables in it. In this paper we show how this model can be used to encode lambda calculus. Individual function applications can be explicitly encoded as lazy or not, as required. We then show how this encoding can be extended to cover functions which manipulate mutable variables, but with the underlying Core Aldwych implementation still using only immutable variables. The ordering of function applications then becomes an issue, with Core Aldwych able to model either the enforcement of an ordering or the retention of indeterminate ordering, which allows parallel execution

Recursive computation of the invariant measure of a stochastic differential equation driven by a L\'evy process

We investigate some recursive procedures based on an exact or ``approximate'' Euler scheme with decreasing step in vue to computation of invariant measures of solutions to S.D.E. driven by a L\'evy process. Our results are valid for a large class of S.D.E. that can be governed by L\'evy processes with few moments or can have a weakly mean-reverting drift, and permit to find again the a.s. C.L.T for stable processes

Process evaluation of Derbyshire Intensive Alternatives to Custody Pilot

The aim of this study was to critically assess the implementation and development of the Intensive Alternatives to Custody (IAC) pilot in Derbyshire. The Ministry of Justice (MoJ) Penal Policy paper (May 2007) outlined the government’s intention to develop higher intensity community orders as an alternative to short-term custody. The IAC Order was subsequently developed and piloted, first in Derbyshire and then in six other areas.* The pilots were centrally funded until March 2011

Meaning in the Process of Signification by the Advertisement of Honda

This study mainly deals with the process of signification in order to reveal how meaning is created by the advertisement of Honda HR-V 2014 through the use of expressions. In this study, “Meaning” is an integrated form consisting the three elements which are denotative form, connotative form, and myth form. Using qualitative content analysis (Schreier, 2012), the writer did this study based on Barthes's process of signification (1987) and Peirce's indexicality (1931-58). From the analysis, the writer found out that meaning is created by indexicality. The index connects the product and the traits that the product possesses. Then, the use of expressions in the advertisement visualises the index of the product. The index which was visualised by the use of expressions which produces denotative meaning and connotative meaning. Those denotative meaning and connotative meaning are perceived by the audiences and creates myth which naturalises the index itself. It can be concluded from this study that meaning is created by the index and has undergone several steps in order for audiences to perceive the myth and become unaware of the index

Existential Process in Harry Potter and the Chamber of Secret: a Systemic Functional Linguistic Study

Dealing with sense of experience people undergo, transitivity construes the process of the experiences. One of the processes in transitivity is discussed here, that is existential process. Qualitatively conducted, this research employs Hallidayan theoretical framework especially transitivity which covers six processes, they are material, mental, verbal, behavioural, relational and the last one is existential process. This process construes existence of matters such as people, things, events, actions and moments which are called as existent. Discussing process, this research focuses on clause because transitivity analysis lies on clauses. Basically, clauses found are not all in form of clause but some of them are taken from clause complex which are then broken down into clauses. Further, there are twenty clauses found engaging existential processes and dummy subject (there). Those processes are auxiliary verb or to be (was and were). Thus far, the existential processes construe two types of existent, they are entity and event. Thirteen of twenty clauses carry out the existent of entity which covers people and things while the rest construe the existent of event which covers action and moment. Another point found is circumstance; there are ten circumstances which are categorized into three types, they are circumstance of place, circumstance of time, and circumstance of manner (comparison)

A better process for a better budget

This policy brief provides a practical solution to facilitate reform of the EU budget decision-making process, overcome the detachment of EU spending from political priorities and increase focus on EU public goods. As the negotiations for the next financial framework are expected to start in less than two years, the window of opportunity for reform is closing rapidly. Additional pressure arises from the need to design a substitute, by Spring 2010, for the Lisbon Strategy that better aligns EU policy goals and spending. For the authors now is the time for reform.

Reframing the EU budget- decision-making process

This paper traces the history of the EU budget and draws lessons for the review to come. Whatever reforms are proposed, the authors believe that they must serve to shift spending to policy areas and instruments where the EU can best add value while at the same time recognising the political need for member states to present EU budget negotiation results in Â?net-balanceâ?? terms. A two-stage negotiation is proposed: first member states should negotiate and agree on what constitute EU public goods. Everything else would thereafter - by default - be deemed redistributive/compensatory spending to be financed on the basis of member statesâ?? current overall net balances.

Sequential biological and photocatalysis based treatments for shipboard slop purification: A pilot plant investigation

This study investigated the treatment of a shipboard slop containing commercial gasoline in a pilot plant scale consisting of a membrane biological reactor (MBR) and photocatalytic reactor (PCR) acting in series. The MBR contributed for approximately 70% to the overall slop purification. More precisely, the biological process was able to remove approximately 40%, on average, of the organic pollution in the slop. Nevertheless, the membrane was capable to retain a large amount of organic molecules within the system, amounting for a further 30% of the influent total organic content removal. However, this affected the membrane fouling, thus resulting in the increase of the pore blocking mechanism that accounted for approximately 20% to the total resistance to filtration (2.85∙10 13 m −1 ), even if a significant restoration of the original membrane permeability was obtained after chemical cleanings. On the other hand, the biological treatment produced a clear solution for the photocatalytic system, thereby optimizing the light penetration and generation of highly oxidizing active oxygen species that enabled the degradation of bio-recalcitrant compounds. Indeed, low total organic carbon (TOC) values (<10 mg L −1 ) were achieved in the output of the photocatalytic reactor by means of only 60 Einstein (E) of cumulative impinging energy after the addition of K 2 S 2 O 8 . Overall, coupling the two processes enabled very high TOC removal (ca. 95%)
