...Operation High Roller Alejo Maciel II March 25, 2015 Introduction Operation High Roller (OHR) was a brazen cyber-attack discovered in January, and made public in July of 2012 by computer security firms McAfee and Guardian Analytics. OHR targeted high balance accounts of both individual consumer and business financial institutions, using a new extensive level of automation built on previously known Trojans Zeus and SpyEye. Although no person or group has ever been identified for the conspiracy and execution of the operation, the attackers were traced to servers performing these attacks in Russia, Albania, and China. According to the McAfee/Guardian Analytics report “Dissecting Operation High Roller,” the firms first identified the group’s initial attack in Italy. Analyzing the attack and identifying the new tactics the group used to successfully target the Italian Bank, the firms found strong evidence of a replication attack against a German bank. It wasn’t until subsequent evidence of attack campaigns within Latin American and the United States were found that the global nature of these attacks was validated (Marcus & Sherstobitoff, 2012). Over an undisclosed time period an approximate amount of $78 million, with a potentially maxed attempt of $2 billion, was successfully siphoned during OHR (Quain, 2012). Analysis The group responsible for these attacks built their tactics on previously existing malware, custom malware, and an in-depth awareness of global...

...or grains, with speed difference and relative rotation of the roller. When the material through a certain distance between the two rollers, the endosperm scraping from wheat skin, and ground into flour. The flour mill noise arising therefrom. In the quality of survival in the market competition, it is very important to reduce the noise. If the design of the flour mill body structure is unreasonable and the processing precision is not high, it will produce noise. When the two parallel rollers rotate in opposite directions, the rolling distance of general milling system is 0.1~0.8mm, the heart grinding system is 0.01~0.05mm. When the radial pulsation is relatively large, then the operation will not stable. Two grinding rollers are not flat, and grinding operation is not stable thus produce noise. The grinding roller is made up of both ends of the roll body is pressed into the shaft machining, the outer layer is chilled alloy cast iron with high hardness, the inner layer is gray. Roller body is longer, the two ends of the hole processing and the middle is not processed, due to the machining error of the roller and the material of the roller body is not uniform, the grinding roller is not balanced and the vibration is generated. The accuracy of the roller bearing is not high, and the design of the parts and the structure of the bearing is unreasonable, all these reason will cause bearing rotation accuracy is not high, short lived and noise increased.

...manufacturing and development experience. Because the two companies shared many of the same customers but had few products in common, customers would surely appreciate that Timken’s sales representatives could meet more of their needs. Timken’s potential annual cost savings from consolidating manufacturing facilities and processes were estimated to be more than $80 million. If the price paid for Torrington were too high, Ingersoll-Rand, rather than Timken, would capture the value of the synergies. In addition, given the large size of the acquisition, Timken was concerned about the impact on its balance sheet. If Ingersoll-Rand demanded a cash deal and if Timken raised the money with new debt, the increased leverage would almost certainly prompt credit agencies to downgrade Timken’s investment-grade rating. The Bearing Industry Bearings of various sizes and specifications found their way into everything from space shuttles to household appliances, automobiles, dentist drills, roller skates, and computer disk drives. In 2001, U.S. establishments involved in ball- and roller-bearing manufacturing employed more than 33,000 workers. The bearing industry was facing a variety of complex problems. Policies favoring the steel industry did not always consider the best interests of the bearing industry, which, as manufacturers of secondary steel products, was in the middle of the production chain. Because bearings were essential components of military and civilian machinery and equipment,...

...Safety Analysis of a High Voltage Test Lab by David Wallace for ISE 6173 Instructor: Dr. Kari Babski-Reeves Spring 2015 ABSTRACT In the production of electrical transformers, dielectric test must be performed to certify the transformer will function properly in the field. These tests are conducted in a high voltage test lab (HVTL) where voltages can reach in excess of 500,000 volts. This health and safety assessment was performed on a HVTL to identify potential safety and health hazards within the lab and apply engineering controls, administrative controls and personal protective equipment to mitigate the hazard. This assessment was accomplished through the use of risk assessment, deviation analysis, job safety analysis, HAZOP and fault tree analysis following a five step method. Each hazard was quantified based on the consequence and the probability of occurring and classified based on the type of risk and the acceptance of the risk. From this analysis, the ten most critical hazards were chosen. These ten were then mitigated using the various controls listed above. * TABLE OF CONTENTS ABSTRACTii INTRODUCTION1 METHODS2 2.1 Safety and Health Analysis Tools2 2.1.1 Risk Assessment Analysis2 2.1.2 Deviation Analysis3 2.1.3 Job Safety Analysis5 2.1.4 Hazard and Operability Analysis5 2.1.5 Fault Tree Analysis6 2.2 Procedures for Five-Step Analysis6 2.2.1 Risk Assessment Analysis of Building and Facility7 2.2.2 Deviation Analysis of Hazardous Substances7 2.2.3 Job Safety Analysis...

...Proceedings of the 2012 International Conference on Industrial Engineering and Operations Management Istanbul, Turkey, July 3 – 6, 2012 Effective Preventive Maintenance Scheduling: A Case Study Hasnida Ab-Samat, Livendran Nair Jeikumar, Ernnie Illyani Basri, Nurul Aida Harun and Shahrul Kamaruddin School of Mechanical Engineering Universiti Sains Malaysia Engineering Campus, 14300 Nibong Tebal, Penang, Malaysia Abstract Maintenance is an important system in operation. In an era where industries are focusing on 24 hours operation to maximize production, machines are pushed to its absolute limits to cope with this demand. As utilization increases, the rate at which the machine parts get worn out increases thus the frequency of failure increases rapidly. To combat this problem and ensure that machines continue to operate at its optimum, maintenance work is carried out. One of the branches of maintenance technique which is carried out to prevent occurrences of failure before it happen is known as Preventive Maintenance (PM). However, performing PM may not be as easy as it requires great cooperation from the maintenance, production and management departments. This paper is written to study the aspects of effective PM and to analyze the causes of inefficient PM activity in a case study company and its implications. Another important approach taken is to investigate the causes of machine downtime by performing a root cause analysis. Affinity diagram was formed to highlight...

...inflation in Thailand affect Blades(assume U.S. inflation remains constant)? ANSWER: A high level of inflation in Thailand relative to the United States could affect Blades favorably. Generally, if a country’s inflation rate increases relative to the countries with which it trades, consumers and corporations within the country will most likely purchase more goods overseas, as local goods become more expensive. Consequently, Blades’ sales to Thailand may increase. 2. How could competition from firms in Thailand and from U .S. Firms conducting business in Thailand affect Blades? ANSWER: Blades would be favorably affected relative to Thai roller blade manufacturers and relative to other U.S. roller blade manufacturers with operations in Thailand. Both groups of firms will likely be forced to raise their prices if they want to maintain the same profit margin should inflation in Thailand increase. This is especially true if both groups of firms source their supplies directly from Thailand, so that the prices of these supplies are subject to the higher inflation is Thailand. Conversely, Blades’ cost of goods sold incurred in Thai and is relatively small . Consequently, costs will not be subject to the higher level of inflation in Thailand to a great extent and Blades will probably not have to raise its prices to the same extent as Thai roller blade manufacturers or U.S. manufacturers with operations in Thailand 6. How could a decreasing level of national income in Thailand affect...

...A paint is composed of pigments, solvents, resins, and various additives. The pigments give the paint color; solvents make it easier to apply; resins help it dry; and additives serve as everything from fillers to antifungicidal agents. Hundreds of different pigments, both natural and synthetic, exist. The basic white pigment is titanium dioxide, selected for its excellent concealing properties, and black pigment is commonly made from carbon black. Other pigments used to make paint include iron oxide and cadmium sulfide for reds, metallic salts for yellows and oranges, and iron blue and chrome yellows for blues and greens. Solvents are various low viscosity, volatile liquids. They include petroleum mineral spirits and aromatic solvents such as benzol, alcohols, esters, ketones, and acetone. The natural resins most commonly used are lin-seed, coconut, and soybean oil, while alkyds, acrylics, epoxies, and polyurethanes number among the most popular synthetic resins. Additives serve many purposes. Some, like calcium carbonate and aluminum silicate, are simply fillers that give the paint body and substance without changing its properties. Other additives produce certain desired characteristics in paint, such as the thixotropic agents that give paint its smooth texture, driers, anti-settling agents, anti-skinning agents, defoamers, and a host of others that enable paint to cover well and last long.
