WILMINGTON, MA — Below is an announcement from the Wilmington Police Department:On October 1, 1962, Congress, by a joint resolution, authorized and requested President John F. Kennedy to designate May 15 of each year as “Peace Officers Memorial Day,” and the week in which it falls as “National Police Week” to pay tribute to the law enforcement officers who have made the ultimate sacrifice for our country and to voice our appreciation for all those who currently serve on the front lines of the battle against crime.In honor of Police Week, members of the Wilmington Police Department will be wearing special patches throughout the month of May. This is the third and final specialty patch that will be worn by our Officers. Patches will be available for sale to the general public for $10 with all proceeds going to the New England Chapter of Concerns of Police Survivors (C.O.P.S.). You can learn about their mission to assist in the rebuilding of the lives of survivors of law enforcement officers killed in the line of duty at https://newenglandcops.org/.Like Wilmington Apple on Facebook.

Citation: Freelance site using software to recruit and pay workers (2010, May 12) retrieved 18 August 2019 from https://phys.org/news/2010-05-freelance-site-software-workers.html Explore further (PhysOrg.com) — Freelancer.com, a freelance site based in Sydney, Australia, has come up with the idea of using software to recruit and pay professionals to carry out work. The site enables software developers to write programs to post job adverts, select from those bidding on the jobs, and even pay them, without any human input.

Microsoft vows openness for mobile app store Matt Barrie, Chief Executive of Freelancer.com, said that after 60 years of people controlling software we are now “getting to the stage where software can control humans.” One possible application of the system could be a company having a large online inventory of virtual goods for sale. The software could stock the store with content created by writers recruited automatically, and those who produced the best-selling product would be selected to create more content. The process could continue as long as the company had money in the bank to continue paying its workers. Barrie said the company was looking forward to “where this might take us.”Barrie said the site has enough programmers on file to make it possible for software to be developed that could even improve itself by hiring programmers to improve its own code, perhaps perpetually. The new software algorithms enabling automatic recruitment, training and paying of workers have just been released for a number of different industries using the site.Barrie said the software algorithms would in many ways ensure performance assessments were more objective, since they are not influenced by subjective factors, such as whether or not the boss likes the worker. Barrie also said in a press release that the system could be used to automatically hire “one, three, or 500 humans,” and that it could “literally assemble an army overnight to solve complex problems.”Automating the hiring process is not an entirely new idea, since many companies now use programs such as TalentFilter to sort through large numbers of applicants to select a short list for interview. In these systems it is quite possible an application or CV is never viewed by a human.There are many outsourcing sites on the Internet, and like the others Freelancer.com has a large membership of people with a wide range of skills such as programmers, Web designers, writers, architects, graphic designers, and so on. Freelancer.com claims to be the largest of these sites, with over 1,500,000 workers registered in 234 countries.The application programming interface (API) is accessible from Freelancer.com.
Explore further (PhysOrg.com) — The many ways in which water differs from other molecules is both a scientific curiosity and an important factor in shaping the Earth. Among water’s unique properties are that it expands when it freezes, it boils and freezes at higher temperatures than expected for a compound with its molecular structure, and it has the ability to absorb large amounts of heat without getting hot. In a recent study, scientists have investigated another unique phenomenon of water called regelation, which occurs when frozen water – or ice – melts under high pressures, even if the temperature is below freezing. Once the pressure is lifted, the water refreezes. The scientists, Teemu Hynninen from the Tampere University of Technology and the Aalto University School of Science and Technology in Finland, as well as coauthors from Finland, Canada, and the US, have performed simulations of the pressure-induced melting of ice by cutting a block of ice with a nanowire. The experiment is similar to a classic experiment performed over a century ago in which scientists demonstrated that a thin, weighted wire could slowly pass through an ice block due to the pressure it exerts on the ice. In the new study, the scientists simulated a nanowire, whose diameter was on the scale of the water molecules, to investigate the molecular-level mechanisms responsible for regelation.“We decided to study the wire-cutting experiment because it has historical signifigance, it is conceptually simple, and it hadn’t been studied on the microscopic scale,” Hynninen told PhysOrg.com. “In this case, we have a wire moving through ice (instead of sliding on it like in normal friction), and the motion is governed by complicated interplay between the wire and the liquid and solid phases of water.” In the simulations, the nanowire is depicted as a string of beads that interact with the H2O molecules. When these beads exert a pressure on the H2O molecules, they break the hydrogen bonds between the oxygen atom of one molecule and the hydrogen atom of another molecule. This breaks the ice lattice structure and transforms the solid ice into liquid water, allowing the nanowire to move through the water, even though the temperature is below freezing. As the scientists explain, the critical point at which the nanowire melts the ice can be thought of as a depinning transition, which generally refers to the yield point of a solid under stress. The simulations showed that this critical point depends on the type of wire used. The scientists compared two types of nanowires – hydrophilic, i.e., a wire whose surface attracts water, and hydrophobic, i.e., a wire whose surface repels water – and found that the wires moved differently through the ice after the depinning transition. Copyright 2010 PhysOrg.com. All rights reserved. This material may not be published, broadcast, rewritten or redistributed in whole or part without the express written permission of PhysOrg.com. The difference is due to the nanowires’ different structural properties, which causes them to interact differently with the surrounding water molecules. The hydrophilic nanowire exhibits a continuous transition at depinning, where the water can easily flow around it, allowing for smooth movement through the ice block. The hydrophobic wire, on the other hand, exhibits a discontinuous transition, where the water builds up thickly on one side of the nanowire. This wire can only move once the water layer builds up high enough so that it reaches the top of the wire, at which point it flows down the other side into a small void, allowing the nanowire to cut through the ice. As the scientists explain, this behavior is somewhat counterintuitive, since a hydrophobic wire might be expected to move more quickly through water than a hydrophilic one due to the latter’s closer water contact and increased friction. However, in this case, the hydrophobic wire’s resistance to water causes it to be partly obstructed by solid ice, giving it more resistance to movement than the hydrophilic wire.“The physically most interesting result we found is that there is a clear difference between the hydrophobic and hydrophilic wires in the way they depin, i.e., how they start moving as the driving force increases,” Hynninen said. “Although the nanowire we use here is a very simple object, our work shows that small structures in contact with water and ice may exhibit unexpected, complicated behavior.” This qualitative understanding and the additional detail provided by the simulations demonstrates how the pressure-induced melting of ice depends on the wetting properties of the object – in this case, the nanowire – applying the pressure. The molecular-scale mechanisms that explain this unique property of water could allow scientists to better understand how the pressure-induced melting and freezing of water has helped shape the Earth. For example, the phenomenon of regelation acts in systems such as glaciers, allowing pressurized ice sheets to flow around obstacles.“This study is basic research, not aimed to solve any particular problem,” Hynninen said. “Having said that, the work is part of a bigger project on the friction of ice at the nanoscale, and there the applications are more obvious. The slipperiness of ice and wet surfaces are significant issues in, e.g., transportation, and better understanding of these phenomena at the microscopic level could help design coatings or microstructures with desired frictional properties for tires, shoes, sports equipment, etc.” Researchers study how ice melts in contact with soil More information: Teemu Hynninen, et al. “Cutting Ice: Nanowire Regelation.” Physical Review Letters 105, 086102 (2010).

Researchers produce first Iraqi-to-English speech-to-speech translation app “No network required,” reads the promotion. “Results appear immediately on your video screen when you need it, anywhere in the world.”Word Lens uses text recognition to work out what the word or phrase is, and automatic-translation software translates it into the new language. The translation is then pasted over the original location. “An optical character recognition engine works with the in-built real time translator to translate foreign phrases for you. The converted text is then displayed on the screen of the smart phone.” © 2012 Phys.org More information: play.google.com/store/apps/det … c3VhbC53b3JkbGVucyJd (Phys.org) — Tuna with hot sauce. Beach closed. Please use caution. Apple users of iOS devices, drawing envy with their cooler than cool apps, have since 2010 enjoyed Word Lens, an application that instantly provides a foreign language translation of a menu or road sign just by the user hovering the device’s camera over the foreign language content in realtime. Now Word Lens is offering its translation app for Android too. The Android app will do translations between English and Spanish, Italian, and French using just the video camera. The nice feature of the app is that network connectivity is not required.

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Otavio Good and John DeWeese from Quest Visual are the two developers behind Word Lens. According to Good, Word Lens tries to find out what the letters are and then looks in the dictionary. Then it draws the words back on the screen in translation. The Android app is offering for purchase translations between English and Spanish, French, and Italian. The introductory price is $4.99 per language.Those testing out Word Lens for the Android platform think it has a way to go. One site said that their brief tests of Word Lens for Android showed it worked well except for rapid flickering of words going back and forth in the translation process. Others described the Android version as having a quirky interface and being shaky and bumpy. Also, said one critique, the app does not work effortlessly in that you need to keep the hand steady and scroll over sentences patiently. Also, phrases have strangled English language word placements, such as “Tongue Bolivian” or “sauce spicy of anchovies” but as a language support tool for visitors to foreign countries it is largely considered as useful. The developers themselves caution that the app will best work with “clearly printed text“ and they note that it does not recognize handwriting or stylized fonts. Good acknowledges weaknesses and says he would be the first to say that the app is not perfect, “but perfect was not the goal,” he added. What is useful, he said, is that “you can get the general meaning.” (Whether it is a spicy sauce or a sauce spicy, you know what is coming.) The app gets good marks elsewhere for speed and useful accuracy. Good says that future plans include introducing more languages. He is also considering a reader for the blind, which would read out loud the words that the app sees on signs. Explore further
