Machine

Technology is a concept rife with confusion. Here, I argue that technologies can be distinguished as a combination of type of producer and an idealized artefact life history. Using this definition, a number of technologies are identified. The first technology historically, in the Protostomes, was the production of individual or family dwellings. Next came objects such as spider webs for trapping prey. Stigmergy followed, with the social insects, as a collective endeavour to construct a mega-structure using simple rules of accretion. Some birds and primates began to make tools, or simple technological objects whose function is closely related to their form. Humans are distinguished by their ability to make machines. Traditional technology took place once people voluntarily organised into groups with specialised knowledge to produce more complex objects and structures. Monumental objects like ceremonial pyramids came with the command economies of the early agrarian societies, which also resulted in a new category of artefact, the network. Finally, with modern civilizations came ad hoc accretion, or population-level adding-on, to make truly complex technological systems. Developing a theoretical framework within which artefacts, production processes and ways of interacting with them are identified should help the study of technology to become more scientific.

A new roll-based process and machine for three-dimensional bending of profiles with symmetrical and asymmetrical cross-sections have been developed. Compared to conventional processes like stretch bending, the advantage of the Torque Superposed Spatial (TSS) bending is the kinematic adjustment of the bending contour, leading to higher flexibility and cost efficiency, especially in small batch production. To define the spatial geometry

The exploitation of cassava tubers (Manihot utilissima) for various industrial, medicinal and food products requires the removal of the cortex, which is commonly carried out manually. Mechanization of this process has the potential of driving increased cultivation of cassava and generating products with high hygienic standard, product quality, processing efficiency, minimum loss of tubers and increased processing rate. The difficulty in achieving an acceptable peeling efficiency can be attributed to: the irregular shape of the tubers, the non uniformity of the cortex thickness and unavailability of technical data on parameters of design. This paper presents the solution to the cassava peeling problems and the development of a new machine capable of peeling cassava tubers with over 90 % efficiency. Cassava tubers have been classified according to their varieties. The varieties have been characterized. The relationship between tuber diameter and cortex thickness is established. These ...

We trained generative models and decision tree classifiers with positive and negative examples of the neo-plastic works of Piet Mondrian to infer his compositional principles, to generate “faux ” works, and to explore the possibility of computer-based aids in authentication and attribution studies. Unlike previous computer work on this and other artists, we used “earlier state ” works—intermediate versions of works created by Mondrian revealed through x-radiography and infra-red reflectography—when training our classifiers. Such intermediate state works provide a great deal of information to a classifier as they differ only slightly from the final works. We used methods from machine learning such as leave-one-out cross validation. Our decision tree classifier had accuracy of roughly 70 % in recognizing the genuine works of Mondrian versus computer-generated replicas with similar statistical properties. Our trained classifier reveals implicit compositional principles underlying Mondr...

This paper presents a full-discretization method based on the direct integration scheme for prediction of milling stability. The fundamental mathematical model of the dynamic milling process considering the regenerative effect is expressed as a linear time periodic system with a single discrete time delay, and the response of the system is calculated via the direct integration scheme with the help of discretizing the time period. Then, the Duhamel term of the response is solved using the full-discretization method. In each small time interval, the involved system state, time-periodic and time delay items are simultaneously approximated by means of linear interpolation. After obtaining the discrete map of the state transition on one time interval, a closed form expression for the transition matrix of the system is constructed. The milling stability is then predicted based on Floquet theory. The effectiveness of the algorithm is demonstrated by using the benchmark examples for one and two degrees of freedom milling models. It is shown that the proposed method has high computational efficiency without loss of any numerical precision. The code of the algorithm is also attached in the appendix.

Mon hypothèse est que la combinaison et la complexification
entretenue par les Lumières entre les trois ou quatre fonctions principales
des automates de cette époque, l’invention mécanique (la
prouesse technique), le modèle scientifique (penser le vivant, « démontrer
plutôt que montrer », écrit Vaucanson à propos de son canard),
mais aussi l’objet d’art ou de curiosité et de foire, enfin, l’objet imaginaire
ou fantasmatique, est précisément un outil de discrimination
des domaines des savoirs et des représentations. L’automate, en
tant qu’il met en oeuvre et en scène tous les degrés de transition entre
les domaines des connaissances et les catégories de la pensée, comme l’organique et le mécanique, l’art et la nature, l’original et le double,
est un outil de questionnement des limites et par là même de reconfiguration des domaines de connaissance. La question n’est alors pas
tant « à quoi servent ces machines ? » que « quel désir viennent-elles
combler, à quel besoin répondent-elles ? »
À partir de ce récit inaugural et exemplaire, j'examine donc l’imbrication des « raisons » de l’automate des Lumières qui conduisent à avancer l’idée d’un « dispositif automate » et, enfin, à proposer une hypothèse de signification – la merveille de substitution au divin.

Hampir setahun saya tidak menulis lagi, bahkan hanya sekedar menengok saja saya jarang hahaha. Hal ini lebih kepada kesibukan saya selama ini di dunia nyata yang masih belajar bekerja sehingga waktu saya habis di kantor dan pabrik, namun Alhamdulillah saat ini saya bisa menulis lagi ^ ^V Kali ini saya tidak akan membahas mengenai software, namun kepada pekerjaan saya di dunia nyata. Kenapa saya mengangkat topik ini?? tidak lain karena ada beberapa temen-temen PKL di tempat saya bekerja, menanyakan beberapa hal mengenai packdev (packaging development). Ceritanya persiapan kompre gitu dech. Sekarang saya akan sedikit mengangkat hal ini (yang penting untuk kompre saja ya), selebihnya bisa dipelajari melalui ebook yang akan saya berikan OK here we goes....... Packdev merupakan salah satu bagian dari departemen riset untuk menentukan kemasan yang aman dan menarik. Packaging sendri salah satu bagian yang paling essensial dalam penjualan baik medis maupun non medis. Jika kemasan disuguhkan menarik, maka kemungkinan untuk terjual akan semakin tinggi (diimbangi dengan marketing yang baik). selain itu, dalam farmasi, tak kalah pentingnya stabilitas obat yang dikemas harus selalu terjaga sehingga obat yang akan dikonsumsi oleh konsumen terjamin secara kualitas. Kemasan obat, ada berbagai macam jenis. Paling umum digunakan adalah strip, blister, sachet dan botol. Strip merupakan kemasan yang terdiri atas dua lembar alumunium (contoh : noza, obat generik seperti dextromethorphan) sementara blister adalah kemasan yang pada satu sisi alu sedangkan sisi lainnya adalah plastik (contoh : panadol atau supra livron). Sachet, hampir sama dengan strip namun isinya lebih ke cairan atau serbuk dan tidak terkotak-kotak (contoh : antimo anak, extra joss) Baiklah, kita bahas kandungan, mesin dan cara pemeriksaanny, tapi strip dan blister saja mengingat hari ini saya akan pergi berenang hhahaha Strip terdiri dari berbagai macam tergantung bahan penyusun dari strip. Setau saya, ada PLM (polycellonium), PLO (Polycello) dan PLN (Polynium). PLM merupakan bahan strip yang paling umum, dimana kandungannya adalah polycello/cellophan dan alumunium. Apakah cellophan?? cellophan adalah sejenis bahan dari serat selulosa yang berbentu tipis transparan, fungsinya dalam kemasan adalah untuk menempelkan pewarna sehingga strip bisa colorfull. Bahan yang biasa dipakai adalah MST / MT dan PT cellophan.Alumunium sendiri berfungsi untuk menjaga obat dari pengaruh kelembapan. Semakin tebal alumunium yang digunakan akan semakin membuat tingkat proteksi menjadi lebih baik. Namun harus dilihat dari sisi mesin strip, apakah kompatibel atau tidak karena bisa jadi semakin tebal akan menggangu proses stripping. Antara selophan dan alumunium ini terdapat satu lapisan yakni PE / Polyetilen yang fungsiny untuk melekatkan selophan dan alumunium. Lapisan setelah alumunium sendiri adalah PE lagi, fungsinya kali ini adalah untuk membuat dua PLM dapat saling melekat saat distripping. Jadi secara garis besar, ada 4 lapisan dalam PLM yakni selophan (terluar), PE, Alu, PE (terdalam). Pembuatan PLM secara garis besar, selophan dicetak dan diberi warna lalu PE dicairkan.

WEKA is a popular machine learning workbench with a development life of nearly two decades. This article provides an overview of the factors that we believe to be important to its success. Rather than focussing on the software's functionality, we r eview aspects of project management and historical development decisions that likely had an impact on the uptake of the

Thinking Otherwise is a unique and revealing look at the philosophical dimensions of information and communication technology (ICT). Among thinkers, the importance of what transpires within the virtual world is the effect these activities have on real human beings who exist outside of and beyond the computer-generated virtual environment. Obviously, the result of ICT interactions can lead to good or bad outcomes.

Gunkel, however, is not concerned about deciding which argument is more compelling, but how these arguments are organized, articulated, and configured. This approach entails challenging, criticizing and even changing the terms and conditions of the discourse itself. For example, the binary nature of computer logic tends to color debate about subsequent moral issues by portraying each side as the antithesis of the other. That is, the switch is either turned on or off.

Thinking Otherwise investigates the unique quandaries, complications, and possibilities introduced by a form of otherness that veils, through technology, the identity of the Other. Therefore, Gunkel formulates alternative ways of proceeding to take into account additional forms of otherness. Gunkel submits traditional forms of philosophical reasoning to a critical reevaluation caused by opportunities made available with information technology and also develops alternative ways of thinking that are oriented otherwise.

----------------------------------------

"Thinking Otherwise will become a classic like Jacques Ellul's Technological Society and Jean Baudrillard's Simulations. This erudite and innovative book totally reorients our thinking away from binary logic. The philosophical dimensions of information and communication technology have never been outlined better. The author is bilingual, knowing both philosophy and ICT's with brilliance. His critique of digital reason and his machine-as-other turn communication ethics on its head. In this post-metaphysical age skeptical of the humanities, Thinking Otherwise demonstrates perfectly how the history of ideas opens up an alternative pathway."

One of the major problems in forming of stainless steel sheet is galling due to lubricant film breakdown leading to scoring and bad surface quality. In a Danish research programme new lubricants substituting the normally applied chlorinated paraffin oils are being developed and tested for this purpose. In order to determine the limits of lubrication of these new lubricants, as well as commercial ones already available on the market, two sheet forming tests have been developed. Quantification of the degree of galling is done by roughness measurements on the workpiece surface. In a strip reduction test, this is done by 2D profilometry at strip locations corresponding to different sliding lengths, whereas a deep drawing test is based on 3D roughness mapping of local areas.

"Resumen - Abstract

Jean-Luc Nancy recorre el cuerpo como una Summa, como un Corpus, lo sustrae del horizonte bio–teleológico del organismo para entregarlo al horizonte del acontecimiento, lo cual implica dejar de pensar en un cuerpo organizado sobre la base de una finalidad separada de sí mismo.
Nancy desarrolla una filosofía del cuerpo en la cual trastoca la interpretación generalmente aceptada en torno al lugar (subordinado) del cuerpo en la constitución del sujeto moderno. De allí que Nancy insista en que “no tenemos un cuerpo, sino que somos un cuerpo”. Así en el nuevo estatuto ontológico y epistémico del cuerpo no sólo se conforman nuevas formas de subjetividad, sino también una “nueva carne”. Así en las fronteras entre lo natural y lo artificial surge la posibilidad de pensar en un cuerpo fragmentado, en un cuerpo cuyos órganos se hayan emancipado, en lo que Deleuze y Guattari llamaron el Cuerpo Sin Órganos. Como se verá el conocimiento del cuerpo nunca es entero y absoluto, sino modal y fraccionado, y la forma del discurso que mejor comporta tal saber es la de un Corpus, precisamente, una cartografía, un inventario de las zonas del cuerpo que brinda un conjunto de acercamientos, revelando lo que el propio Nancy llamó “indicios del cuerpo”. De este modo lo que interesa en Corpus no es el todo orgánico, sino las partes desprendidas y sus posibles, en cuanto múltiples, relaciones.
Paralelamente se examinará el pensamiento posthumanista, desarrollado por Sloterdijk, sus fuentes filosóficas y sus medios técnicos, para luego  abordar –desde allí el problema de la alteridad,  la reconfiguración de la subjetividad y la ontología del cuerpo tal como es propuesta por Jean–Luc Nancy. De este modo se revisará el  fenómeno de la histeria anti-tecnológica; las metáforas y escatología de la enfermedad, profundizando la vivencia del trasplantado, para terminar discutiendo las consecuencias éticas de esta suerte de ontología del cuerpo que comienza a configurarse, una ontología modal –si se quiere– ya que el cuerpo dice relación más con con posiciones, tensiones, y pesos, que con esencias o sustancias."
