On the Taylor expansion of $\lambda$-terms and the groupoid structure of their rigid approximants

We show that the normal form of the Taylor expansion of a $\lambda$-term is isomorphic to its B\"ohm tree, improving Ehrhard and Regnier's original proof along three independent directions. First, we simplify the final step of the proof by following the left reduction strategy directly in the resource calculus, avoiding to introduce an abstract machine ad hoc. We also introduce a groupoid of permutations of copies of arguments in a rigid variant of the resource calculus, and relate the coefficients of Taylor expansion with this structure, while Ehrhard and Regnier worked with groups of permutations of occurrences of variables. Finally, we extend all the results to a nondeterministic setting: by contrast with previous attempts, we show that the uniformity property that was crucial in Ehrhard and Regnier's approach can be preserved in this setting.

Machine Learning Based Heat Transfer Optimization of Nano-fluid flow in a Helically Coiled Pipe

Machine Learning algorithms are widely used in various fields such as energy sectors, manufacturing sectors and aerospace sectors. These algorithms are used mainly in predictive and optimization purpose. The present study deals with the application of two machine learning algorithms i.e. Random Forest algorithm and Support Vector Machine Algorithm to predict the heat transfer efficiency of a flowing nano-fluid in a helically coiled pipe.

Transliteration: A Magnetic Analysis

Machine transliteration is an important problem in an increasingly multilingual world as it plays a critical role in many downstream applications such as machine translation or cross-lingual information retrieval systems. There is now a vast amount of information accessible via the Internet where a lot of regional and cultural information is put on the World Wide Web in different languages and scripts. There are more that six thousand living languages in the world. Adding to the diversity is the fact that some languages are written in different scripts in different regions of the world. The multitude of foreign languages and mutually incomprehensible scripts of the same language pose a barrier to information exchange as we cannot all learn every language or script in use worldwide. Therefore, if we can get around the language barrier or at least the script barrier, we can access much more of the world's culture and can explore its abundant richness.

Embedded Machine Learning and Embedded Systems in the Industry.

Machine learning is the buzz word right now. With the machine learning algorithms one can make a computer differentiate between a human and a cow. Can detect objects, can predict different parameters and can process our native languages. But all these algorithms require a fair amount of processing power in order to be trained and fitted as a model. Thankfully, with the current improvement in technology, processing power of computers have significantly increased. But there is a limitation in power consumption and deployability of a server computer. This is where “tinyML” helps the industry out. Machine Learning has never been so easy to access before!

The Mechanics of Order: An Inquiry into the Utopian Possibilities of the Free and Open Source Ecology

<p>This is a study that concerns itself with two questions: how is order produced? and, is this order desirable? Contrary to many utopian methodologies that seek to elaborate 'what is not' but which 'ought to be', this is a study that seeks to contribute to a utopian mechanics by way of studying extant subterranean practices or ' minor traditions,' by studying elements of 'what is' that may also form something of what 'ought to be.' This study takes as its principal task to understand the production of order within a small free and open source project known as Compiz. It borrows from Michel Foucault, Gilles Deleuze and Felix Guattari to formulate the related concepts of the machine and the abstract machine in order to account for the ongoing production of order. These two concepts, following the lead of Bruno Latour, adhere to a 'flat social' ontology and bring forth the world of objects and space as being indispensible, alongside the members of Compiz, in accounting for the project's ordering. The study poses three primary machines of order: the Passport, the Exodus and the Module. The Passport regulates access within the virtual spaces of Compiz and produces a role known as the 'gatekeeper,' one who may exercise a power both vicarious and precarious. The machine of the Exodus makes the threat of desertion a real and ongoing possibility and in this establishes an 'imaginary counter' within the group, undermining the power of the gatekeeper and recasting him as a steward of the code, as 'maintainer.' The third machine, known as the Module, is designed to minimise the complexity of the project by way of the spatialisation and organisation of the code, but subsequently effects a concomitant spatialisation and organisation of developers and projects, coming in the end to shape the large scale order amongst free and open source projects. The study concludes by suggesting a 'present tense' and 'open ended' conception of utopia, in which both the machines of the Exodus and the Module - but not the Passport- would find themselves well placed.</p>

Slotted ALOHA Protocol for Next Generation IoT

Machine to Machine (M2M) communication is used to maintain the connectivity between the various devices in IoT. One of the major issues of Machine to Machine (M2M) communications is to enhance the network lifetime with the help of an efficient MAC protocols. Slotted ALOHA Protocol is simple random access technique used in low power applications like LoRaWAN (Long Range Wireless Area Network). This approach gives an improved result as compared to P-persistence slotted ALOHA. In this paper, we consider an IoT -M2M network comprises of a large no of devices that transmit data packets to a gateway. We have tried to reduce the collision, which directly reduce retransmission of data packets. We propose Adaptive pSlotted ALOHA Protocol using Successive Interference Cancellation (SIC). It offers high throughput and reduces the delay. It is the simplest way of the channel allotment among the users. The proposed p-Slotted ALOHA protocol using SIC is better than the p-persistence slotted ALOHA in term of delay and throughput. Keywords: MAC, M2M, Slotted ALOHA, LoRa-WAN, IoT, SIC

IMPLEMENTASI DETERMINISTIC FINITE AUTOMATA (DFA) PADA PERANCANGAN APLIKASI PERHITUNGAN UANG HARIAN PERJALANAN DINAS KEMENTERIAN

Each ministry always has a budget for official travel, especially for the daily money given to personnel who travel in exchange for daily expenses. With the current pendemi need to be held an application system that can reduce contact when handling official travel files. The design of this application will use the implementation of Deterministic Finite Automata (DFA) as an abstract machine to determine the state or stages to determine the transition between these stages to determine the daily money calculation of official travel. From the calculation of daily money will be made recapitulation to be verified and if it is considered appropriate and correct will be transferred to the account that travels to the office. This is the role in making abstract machines for the calculation of daily money using Deterministic Finite Automata (DFA) because each stage is right to one stage next until the last stage that prints proof of transfer.

Random Technology

Modern technology increasingly uses randomness to avoid lockstep behaviour and the suppression of unwanted regularity. The nature of noise is explored, and in particular the use of noise to obscure unwanted signals, either explicitly, using techniques like jitter or dither, or in the abstract. Machine-learning techniques rely on randomness to explore the solution space of a problem. Simulated evolution can be an effective way to tackle design problems, and relies on randomness.
