...If you’ll bear with me for mixing metaphors, the title of this blog describes to a tee the situation the U.S. Federal Reserve (Fed) and Fed Chair Janet Yellen find themselves in with other central banks, including Bank of Japan (BOJ) Governor Haruhiko Kuroda. Let us start with January’s Federal Open Market Committee (FOMC) meeting. If one were optimistic, one could describe the FOMC communique as dovish, and there is enough in the note to support that line of thinking. The FOMC mentions slowing growth, although more in inventory terms rather than spending and investment. It also mentions global developments but passes on balance-of-risk statements. However, if one were a little less optimistic, the repeated comments on the strength of the U.S. labor market might make one nervous. What the FOMC was in essence saying is that yes, the U.S. economy was slowing in the fourth quarter of 2015, and yes, global and financial market developments have them worried, but there is enough strength in the U.S. labor market for them not to back off from their tightening stance. The bottom line, from my perspective, is that while the Fed may seem to be sounding a tad dovish, unless the labor market starts softening, Fed policymakers are far from done with tightening. As a result, while there are reasons to be hopeful for risky asset prices, it is far from certain that the Fed will stop tightening now and a reversal of the markets’ thinking on what the Fed will do – which at the moment...

...we describe polynomial functions and look at some of their properties. In order to master the techniques explained here it is vital that you undertake plenty of practice exercises so that they become second nature. After reading this text, and/or viewing the video tutorial on this topic, you should be able to: • recognise when a rule describes a polynomial function, and write down the degree of the polynomial, • recognize the typical shapes of the graphs of polynomials, of degree up to 4, • understand what is meant by the multiplicity of a root of a polynomial, • sketch the graph of a polynomial, given its expression as a product of linear factors.

Roots of polynomial functions 2 2 3 6 7 www.mathcentre.ac.uk 1 c mathcentre 2009 1. Introduction A polynomial function is a function such as a quadratic, a cubic, a quartic, and so on, involving only non-negative integer powers of x. We can give a general defintion of a polynomial, and define its degree. 2. What is a polynomial? A polynomial of degree n is a function of the form f (x) = an xn + an−1 xn−1 + . . . + a2 x2 + a1 x + a0 where the a’s are real numbers (sometimes called the coefficients of the polynomial). Although this general formula might look quite complicated, particular examples are much simpler. For example, f (x) = 4x3 − 3x2 + 2 is a polynomial of degree 3, as 3 is the highest...

The other parts of Automated Food Serving System are two tables and four magnets which are used to turn and stop the vehicle in the required position with help of reed sensor. 2.2 Process Description When the staff in the kitchen places the food on the tray of AGV and confirms the table number, the AGV will start its navigation through the metallic path by sensing the copper strip. If the AGV goes out of the path the stepper motor will automatically activate and return the vehicle to its correct track. While navigation, the AGV will count the magnets which are placed on the turning points and will compare the counted number with the entered table number. If the entered table number matches with the magnet count, the vehicle will take 90 degree left turn and will continue its navigation until it detects the next magnet....

...Fractional distillation was used to separate an ethanol mixture and determine the percent of ethanol. A fractional distillation apparatus with copper turnings in the fractionating column was used to separate the ethanol mixture. The mixture was heated to a boil (78.1*C) and began to drip distillate into the receiving flask. A sample of the distillate was taken and a pipet was used to measure out 1 mL of the substance. The weight of the 1 mL was determined to be 0.82grams. The density of the sample was calculated at 0.82g/mL of ethanol. The percentage of ethanol solved to be 85% ethanol. Introduction The purpose of this experiment was to identify the unknown percentage of ethanol in the ethanol mixture. Fractional distillation was used to separate the ethanol mixture into two components. The copper turnings in the fractional distillation column allowed for the vapors from the boiling mixture to be repeatedly filtered through the system. The repeating of the vapor process is what allows for separation of two components in a mixture with close boiling points. By separating the mixture between precise boiling points and then collecting a sample of the distillate from the round bottom receiving flask to weigh, the density can be determined. With the density known the ethanol percentage can be easily determined with table on page 129, (Pavia, Small Scale Approach to Laboratory techniques). Results To determine the percent of the ethanol in the mixture, a sample...

We waited for three minutes before turning it back on. The water from the slide was absorbed by placing a Kimwipe at the edge and allowing the wipe to absorb the water. Fresh water was then added with a dropper. We counted the heart rate for ten seconds and recorded the data. We absorbed with water again with the Kimwipe and added fresh water before turning off the microscope and letting the D.magna rest for three minutes before turning the microscope back on and repeating the steps two more times. After getting the data with the water we repeated the same procedure but introduced a 5% alcohol solution instead of water before counting the heart rate. We repeated with procedure with the alcohol solution three...

...Assistant Professor Division of Transportation and Logistics System Engineering Yosu National University San 96-1, Dundeok-dong, Yosu city Chunnam, 550-749, KOREA Fax:+82-061-659-3340 E-mail:limyt@yosu.ac.kr Hyunmyung KIM PhD Student Department of Civil Engineering Institute of Transportation Studies University of California, Irvine USA Fax: (949) 824-8385 E-mail: hyunmyuk@uci.edu Abstract : Existing k-shortest path algorithms has some weaknesses such as path similarity among determined paths and network expansion for describing turn prohibitions. Path similarity represents that many of the alternative paths derived from the k-shortest path algorithm are likely to share a lots of links, so they could not represent heterogeneity. The turning restrictions popularly adopted in real road may violate Bellman’s principle of optimality in searching shortest path, so network expansion technique is widely used to avoid such difficulty. But, this method needs additional works to expand the network. This paper proposes a link-based shortest path algorithm to generate dissimilar paths for the travel information in real road network where exists turn prohibitions. The main merit of proposed model is to provide efficient alternative paths under consideration of overlaps among paths to alleviate the path similarity. Another merit is that it does not require extra nodes and links for expanding the network. Thus it is possible to save the time of network modification and of computer running...

...exhausted and completed; the last of the last that is remaining being grabbed by the richest that are able to afford it by paying a huge premium for it. It sounds like a situation that will happen in far future, but all of us need to realize and be aware of the fact that the so called ‘far future’ is just 4 decades away. Can we envision a world sustaining without oil reserves? Can we still be ignorant of the fact that the oil reserves are getting completely drained up in the near future? Can we still continue comfortably the same level of oil consumption? One needs to act upon to save the oil, use it very meticulously and postpone the exhaustion of the oil reserves by as much as possible. All of it can start with initiative as simple as - • Turning off the engine of motor vehicles while one idles at the Traffic Light Though it seems to be very small saving, it will definitely make a big difference when considered holistically. And studies did reveal the benefits of such actions. Such small initiative will not only result in saving of the oil but also gives many other cascading benefits. But all it needs is awareness and realization in the general public. If we can successfully market the cause and call for the action, the public will definitely join hands. In India, domestically the oil production is roughly 0.69 million barrels per day. But the demand for oil is 2.2 million barrels per day. Hence, only 30% of the demand is met by the domestic oil reserves and the excess 70% of the...

...My Room When walking through the door you have arrived at my home, the place where I eat, sleep, invite friends and just generally be. Before noticing any smell, decoration or furniture it is likely that you will be welcomed by my one year old pug. The first room where I spend most of my time, the living room and kitchen, is rectangular with sand colored tile and four white walls all naked except for a glass clock with black dots marking each hour. Still standing in the door, trying to zone out my pug which loves attention, you will see an ivory-white legged dining table with a jet-black glass top converted to my working desk and next to it a white stuffed chair with black legs. In the middle of the room is a black, leather clad sofa with an adjustable back. Although it looks flat and uncomfortable, sitting down you will feel it is soft enough to sleep on. In front of the sofa is a non-peculiar white coffee table, just big enough to house a couple of glasses, a book and some snacks. On the opposite side of the sofa is a flat-screen TV resting on one of those IKEA TV compartments, this one being brown colored and without doors. Sitting in the sofa, to your right, is a big basket made from rotting wood filled with books, mostly fictional crime or thrillers, a few months’ worth of Vanity Fairs and chargers to various devices in my belonging. After this, behind a glass wall and door is my kitchen. Looking straight ahead is the room’s only window, big and wide enough to light up the...

I did this by buying and collecting books to donate to the libraries that serve Turning Point Academy students in order to increase their reading opportunities and their learning environment. This project has reminded me that reading is a joy that belongs in every one’s life and should be considered a privilege more than as a right. Reading is amazing. In fact, amazing doesn’t even begin to describe how unbelievably valuable reading is in one’s life. The dictionary definition of reading is “the action or skill of reading written or printed matter silently or aloud,” (Webster’s Dictionary). This definition doesn’t adequately describe reading because it does not fully portray the valuable benefits...

...pattern, the allowances commonly considered are discussed below. 1. Shrinkage Allowance Generally metals shrink in size during solidification and cooling in the mould. So casting becomes smaller than the pattern and the mould cavity. Therefore, to compensate for this, mould and the pattern should be made larger than the casting by the amount of shrinkage. The amount of compensation for shrinkage is called the shrinkage allowance. Generally shrinkage of casting varies not only with material but also with shape, thickness, casting temperature, mould temperature, and mould strength. Therefore, it is better to determine the amount of shrinkage according to the past record obtained from many experiences. Table 1.2 shows an average amount of shrinkage for important cast metals. Table 1.2 Typical shrinkage allowances for important casting metals Type of metal Amount of shrinkage (%) Grey cast irons 0.55-1.00 White cast irons 2.10 Malleable cast irons 1.00 Steels 2.00 Manganese steel 2.60 Magnesium 1.80 Type of metal Zinc Brasses Bronzes Aluminium Aluminium alloys Tin Amount of shrinkage (%) 2.60 1.30-1.55 1.05-2.10 1.65 1.30-1.60 2.00 In practice, pattern makers use a special rule or scale, called the “pattern maker’s contraction rule”, which, after providing with necessary allowance, is slightly longer than the ordinary rule of the same length. The graduations are oversized by a proportionate amount, for example, when constructing a pattern for aluminium alloys, the pattern maker...

...SR-ht-003 Documentation Entities and Attributes When writing application programs and designing databases the first step is traditionally to document program logic into what is known as flowcharts, object diagrams, and data models. Before this can be done you must first decide which technique you are going to use. The most popular form of data models is what’s known as entity-relationship model (ERD) which was designed and published for the first time ever by Peter Chan in 1976. The basic components that make up and ERD are entities, attributes, identifiers, and relationships. Entities (real world object, semantic object, physical thing, logical abstraction) are something that the user wants to keep track of and are classified and grouped as an entity class, entity classes are always capitalized. There are also different variations of entities, strong and weak. A weak entity cannot exist in a database unless another entity exists also. Anything that is not a weak entity has to be a strong entity. It is also important to follow entity integrity, an important constraint meaning that no two records are identical or duplicates (no duplicate primary keys and non-null values). Next up is what’s known as the entity instance. First you must be able to distinguish the difference between an entity class and an entity instance. The difference between the two is that an entity class is a collection of entities described by the structure of entities in its class. There are usually...

Before any analysis, some sort of scope should be provided at the beginning of any business report. A tree diagram is useful because:➢ A tree-diagram defines the scope and product-category structure of the “industry” of concern. ➢ Depicts aspects of an industry that are close together ➢ Showing which parts belong together ➢ Displaying both broad and narrow options ➢ Identifying the scope for the current report. The following could be used by a company such as Coca-Cola:Beverages Alcoholic Non-Alcoholic Hot Juice Milks ! Colas Cold Softdrink Energy Lemonade Water Other Flavours This diagram shows that the “industry” could be defined as: • Beverages (the broadest definition) • Non-Alcoholic beverages • Cold non-alcoholic beverages.
