Älylasien hyödyntäminen yrityksen sisäisessä logistiikassa : kannattavuus ja mahdollisuudet

Älylasit ovat puettava älylaite, jotka pystyvät älypuhelimen tavoin käsittelemään viestiliikennettä ja antamaan käyttäjälle tarpeelliset tiedot näkyviin silmän eteen. Tätä kutsutaan myös täydennetyksi todellisuudeksi. Opinnäytetyön tarkoituksena on selvittää edellytyksiä ja kannattavuutta uuden älylasiteknologian käyttöönottamiselle yrityksen sisäisessä logistiikassa. Työn alussa käsitellään sisäisen logistiikan käsitettä, sekä varastoinnin tyypillisiä työvaiheita, joihin älylaseja voitaisiin soveltaa. Varaston toimintaa käsitellään myös kustannusten ja laadun kannalta. Myöhemmissä kappaleissa tutustutaan älylaseilla jo tehtyihin pilottiprojekteihin sisäisessä logistiikassa, sekä älylasien laitetarjontaan. Älylasien kannattavuutta varaston toiminnassa tutkitaan investointilaskelmien kautta, jonka ytimessä on työajan säästö, jonka älylasien käyttö tarjoaa. Työajan säästö on arvioitu MOST -työntutkimusmenetelmällä. Näiden laskelmien pohjalta älylasien käyttööntotto olisi kannattavaa, mutta alkuarvojen mahdolliset muutokset tekevät suuren vaikutuksen hankkeen kannattavuuteen, kuten herkkyysanalyysi osoittaa. Siksi ennen pilotointivaihetta yrityksen tulee tarkemmin selvittää hankkeen kannattavuus vastaavilla menetelmillä, sillä älylasien käyttöönotto sisältää tällä hetkellä paljon kiinteitä kuluja.Smart glasses are a wearable smart device which are capable of handling communication and information as modern smart phones. They also display useful information in front of the user’s field of vision. This is also called as augmented reality. The purpose of this thesis is to research the possibilities and feasibility of using smart glasses in the internal logistics operations of a company. In the beginning of this thesis the concept of internal logistics is addressed, as are the typical operations within the warehouse where the smart glasses technology can be applied into. Warehouse operations are also addressed from the cost and quality perspective. The later chapters look into a pilot projects already done with smart glasses and also the current device selection of smart glasses. The feasibility of smart glasses in internal logistics is determined with investment calculations. The saved working time is in the core of these calculations, which is estimated using the MOST work research method. According to these investment calculations the introduction of smart glasses in the internal logistics would feasible, but the possible changes in the initial values would make significant impact on the feasibility as the sensitivity analysis shows. That is why before a company should assess more closely the feasibility with similar methods before starting the pilot project with smart glasses. This is mostly because industrial use of smart glasses currently creates a lot of fixed costs

Updraft : crafting a new passive cooling

To comfortably inhabit historic buildings we have developed mechanical devices to manage the internal environment so that it is possible to keep the room temperature stable despite season and climate. However, enormous energy is necessary to sustain these machines, which poses practical and environmental problems. To overcome and prevent this waste, efforts have been made to control the internal environment of contemporary buildings using natural principles. Is it possible to use this approach to improve the performance of historic buildings without compromising character or significance? This is an ideal topic to test against RISD campus buildings. The campus is made up primarily of buildings built over 100 years ago, and most are structurally and mechanically vulnerable. The majority of buildings are insulated from the exterior wall, while the insulation of the windows and the efficiency of the air conditioning and ventilation systems are inadequate. Based on analysis of the age and inefficiency of each building, the Metcalf Building must be addressed, as the analysis shows that Metcalf has many overheated departmental spaces. There is no air-conditioning facility and the effectiveness of ventilation is not properly maintained. This problem eventually causes the temperature and humidity to rise excessively due to heat emitted from people and machines. If we develop conventional facilities to resolve this, it will consume an enormous amount of energy to maintain the indoor environment, and spatial losses can not be avoided. How can we resolve heating and cooling the Metcalf Building without creating other issues? This problem can be effectively overcome by applying the principle of air convection to a building. Air convection is the circular motion that occurs when warmer air — which has faster moving molecules, making it less dense — rises, while the cooler air drops. Using this principle, the hot air inside the building is discharged to the outside, and the cold air from outside is sucked in to create a natural air-conditioning and ventilation system. An example of this phenomenon is the termite habitat: termites circulate air using the temperature difference between the habitat and the ground. Through this difference in temperature, the cold air continues to be supplied to the inside of the habitat, and the heated air from the inside is discharged to the outside. The same principles will be applied to the Metcalf Building. First, install ceiling panels that will allow air circulation inside the building. Second, the double facade is used to create a passage for air flow. Cold air and hot air will move through this passage. The cold air flowing from the back of the building passes through the ceiling panels of each floor and is then discharged outside. Finally, electricity is produced using the speed at which the discharged air flows. The energy thus generated is used to help air circulate inside the building. In doing so, the room temperature can be efficiently maintained using only a small amount of energy without changing the essential character of the historic building

Wireless Internet Searches: How the Fourth Amendment Applies to Police Searches of Information Accessed over a Wireless Internet Connection

In a series of rulings by the U.S. District Court for the District of Oregon and the Ninth Circuit Court of Appeals, it is suggested that a person may not have an expectation of privacy in some computer files that are accessible through a secured, or unsecured, wireless network. This Note uses the reasoning in these court decisions to create a framework for analyzing the Fourth Amendment\u27s application to secured and unsecured wireless Internet networks. This Note concludes that the trespass analysis derived from United States v. Jones would establish a more predictable and functional standard when analyzing a search of a wireless Internet network. This is because the court can focus on what matters: the constitutional protection of the area that contains the wireless network

Ironic and Absurd Discourse of Dress and Appearance on Social Media

The purpose of this paper is to interpret how absurdity can be ironic through dress and appearance. By using two popular culture examples, one contemporary and one from the 1990’s, I look at how existential philosophies impact comparisons to society and how their reactions of dress and appearance can be ironic. This paper discusses Lee Alexander McQueen and Austin Babbitt (AssPizza) to find the intersection of irony, absurdism, social comparison, and dress and appearance. These two examples prove irony can be interpreted through an understanding of existentialism and how one views society and if they draw comparisons to their peers. McQueen and Babbitt–aligning with philosophers like Friedrich Nietzsche and Albert Camus–are unique as individuals within their respective practices, but aspects of their ideologies and irony can be seen across society today

Manipulation of ruminal fermentation to alter milk fatty acid composition in dairy cows

The objective of this study was to determine the effects of method of barley grain processing (dry-rolled vs. pelleted barley) and source of oilseed (ground canola vs. ground flaxseed), arranged as a 2 x 2 factorial, on feed intake, ruminal fermentation, nutrient flow to the duodenum, and milk production and composition in dairy cows. Eight Holstein cows (655 ± 69 kg; 83 ± 16 DIM) were used in a replicated 4 x 4 Latin square with 28-d periods. Cows in one square were fitted with ruminal and duodenal cannulae. Cows fed dry-rolled barley consumed 1.8 to 3.5 kg/d more (P = 0.02) DM than those fed pelleted barley; however, source of supplemental dietary fat had no effect on DM intake. Ruminal pH was lower (P = 0.045) in cows fed pelleted barley compared to those fed dry-rolled barley. Ruminal concentration of acetate was greater (P = 0.001), whereas ruminal concentration of propionate tended to be lower (P = 0.11), in cows fed dry-rolled barley compared to those fed pelleted barley; consequently, the acetate:propionate ratio was higher (P = 0.01) in cows fed dry-rolled barley compared to those fed pelleted barley. Ruminal concentration of total VFA was unaffected (P > 0.05) by diet. Source of dietary fat had no effect on ruminal digestion of OM, NDF, ADF or starch; however, ruminal starch digestion was slightly higher in cows fed pelleted barley compared to those fed dry-rolled barley (90.8 vs. 89.5%). Total dietary fatty acid intake was higher (P 0.05) by diet; however, milk fat content was higher (P = 0.004) in cows fed dry-rolled barley compared to those fed pelleted barley. Milk fat content of C18:3 was higher (P = 0.005) in cows fed canola compared to those fed flax. Milk fat content of C18:3 and cis-9, trans-11 C18:2 were higher in cows fed pelleted barley compared to those fed dry-rolled barley with flax as the source of oilseed, but not with canola (interaction, P < 0.01). Milk fat content of saturated fatty acids decreased (P < 0.001) and that of polyunsaturated fatty acids increased (P = 0.003) in cows fed pelleted barley compared to those fed dry-rolled barley. In summary, milk fatty acid profiles were altered by method of grain processing and source of oilseed

Ventral hippocampal muscimol disrupts context-specific fear memory retrieval after extinction in rats

Research aimed at understanding Pavlovian fear memory extinction has yielded considerable insight into the conditions under which fear memories may become inhibited. After extinction, Pavlovian fear memory retrieval is context-specific. Fear memories are not expressed in the extinction context, but they are expressed in every other context. Research indicates that the dorsal hippocampus mediates the context-specific expression of fear memory, but the role of the ventral hippocampus in mediating this process is unknown. Insofar as the ventral hippocampus is involved in the acquisition and expression of both context and tone fear, we asked whether GABA systems in the ventral hippocampus mediate context-specific fear memory retrieval after extinction. Experiment 1 showed that ventral hippocampal inactivation with muscimol disrupted context-specific fear memory retrieval. Experiment 2 showed that rats infused with muscimol can discriminate a context in which they were shocked from a neutral context. Nonetheless, they do appear to have a mild impairment in this task. Experiment 3 showed that ventral hippocampal muscimol did not disrupt locomotor activity, but did result in a slight increase in freezing and grooming, an effect that cannot explain the context-specific retrieval deficit demonstrated in experiment 1. These data are consistent with a role for the ventral hippocampus in mediating context-specific fear memory retrieval. © 2005 Wiley-Liss, Inc.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/49533/1/20144_ftp.pd

Long-time behavior towards viscous-dispersive shock for Navier-Stokes equations of Korteweg type

We consider the so-called Naiver-Stokes-Korteweg(NSK) equations for the dynamics of compressible barotropic viscous fluids with internal capillarity. We handle the time-asymptotic stability in 1D of the viscous-dispersive shock wave that is a traveling wave solution to NSK as a viscous-dispersive counterpart of a Riemann shock. More precisely, we prove that when the prescribed far-field states of NSK are connected by a single Hugoniot curve, then solutions of NSK tend to the viscous-dispersive shock wave as time goes to infinity. To obtain the convergence, we extend the theory of $a$-contraction with shifts, used for the Navier-Stokes equations, to the NSK system. The main difficulty in analysis for NSK is due to the third-order derivative terms of the specific volume in the momentum equation. To resolve the problem, we introduce an auxiliary variable that is equivalent to the derivative of the specific volume
