Administrative divisions of Texas

Texas has a total of 254 counties, many cities, and numerous special districts, the most common of which is the independent school district.

County

Texas has a total of 254 counties, by far the largest number of counties of any state.

Each county is run by a five-member Commissioners' Court consisting of four commissioners elected from single-member districts (called commissioner precincts) and a county judge elected at-large. The county judge does not have authority to veto a decision of the commissioners court; the judge votes along with the commissioners (being the tie-breaker in close calls). In smaller counties, the county judge actually does perform judicial duties, but in larger counties the judge's role is limited to serving on the commissioners court and certifying elections. Certain officials, such as the sheriff and tax collector, are elected separately by the voters, but the commissioners court determines their office budgets, and sets overall county policy. All county elections are partisan, and commissioner precincts are redistricted after each ten year Census both to equalize the voting power in each and in consideration of the political party preferences of the voters in each.

Administrative divisions of Wisconsin

The administrative divisions of Wisconsin include counties, cities, villages and towns. In Wisconsin, all of these are units of general-purpose local government. There are also a number of special purpose districts formed to handle regional concerns, such as school districts.

Whether a municipality is a city, village or town is not strictly dependent on the community's population or area, but on the form of government selected by the residents and approved by the Wisconsin State Legislature. Cities and villages can overlap county boundaries, for example the city of Whitewater is located in Walworth and Jefferson counties.

County

The county is the primary political subdivision of Wisconsin. Every county has a county seat, often a populous or centrally located city or village, where the government offices for the county are located. Within each county are cities, villages and towns. As of 2015, Wisconsin had 72 counties.

A Board of Supervisors is the main legislative entity of the county. Supervisors are elected in nonpartisan elections for two-year terms (except in Milwaukee County where the Milwaukee County Board of Supervisors served four years). In May 2013, the Wisconsin Legislature passed a bill that will reduce the terms of office from four-years to two-years for the Milwaukee County Board of Supervisors. The type of executive official in each county varies: 11 counties have a County Executive elected in a nonpartisan election for a four-year term; 20 counties have appointed County Administrators; and 41 have appointed Administrative Coordinators. Other officials include sheriffs, district attorneys, clerks, treasurers, coroners, surveyors, registers of deeds, and clerks of circuit court; these officers are elected for four-year terms. In most counties, elected coroners have been replaced by appointed medical examiners. State law permits counties to appoint a registered land surveyor in place of electing a surveyor.

City (Jane Siberry album)

City is a 2001 album by Jane Siberry.

It is a collection of songs which mostly had not previously appeared on a regular Siberry album, comprising tracks that she recorded for movie soundtracks or in collaboration with other artists.

Core (manufacturing)

A core is a device used in casting and molding processes to produce internal cavities and reentrant angles. The core is normally a disposable item that is destroyed to get it out of the piece. They are most commonly used in sand casting, but are also used in injection molding.

An intriguing example of the use of cores is in the casting of engine blocks. For example, one of the GM V-8 engines requires 5 dry-sand cores for every casting.

Advantages and disadvantages

Cores are useful for features that cannot tolerate draft or to provide detail that cannot otherwise be integrated into a core-less casting or mold.

The main disadvantage is the additional cost to incorporate cores.

Requirements

There are seven requirements for core:

Lithic core

In archaeology, a lithic core is a distinctive artifact that results from the practice of lithic reduction. In this sense, a core is the scarred nucleus resulting from the detachment of one or more flakes from a lump of source material or tool stone, usually by using a hard hammer percussor such as a hammerstone. The core is marked with the negative scars of these flakes. The surface area of the core which received the blows necessary for detaching the flakes is referred to as the striking platform. The core may be discarded or shaped further into a core tool, such as can be seen in some types of handaxe.

The purpose of lithic reduction may be to rough out a blank for later refinement into a projectile point, knife, or other stone tool, or it may be performed in order to obtain sharp flakes, from which a variety of simple tools can be made. Generally, the presence of a core is indicative of the latter process, since the former process usually leaves no core. Because the morphology of cores will influence the shape of flakes, by studying the core surface morphology, we might be able to know more information about the dimensional flake attribute, including their length and thickness. Cores may be subdivided into specific types by a lithic analyst. Type frequencies, as well as the general types of materials at an archaeological site, can give the lithic analyst a better understanding of the lithic reduction processes occurring at that site.

Intel Core 2

Core 2 is a brand encompassing a range of Intel's consumer 64-bit x86-64 single-, dual-, and quad-core microprocessors based on the Core microarchitecture. The single- and dual-core models are single-die, whereas the quad-core models comprise two dies, each containing two cores, packaged in a multi-chip module. The introduction of Core 2 relegated the Pentium brand to the mid-range market, and reunified laptop and desktop CPU lines, which previously had been divided into the Pentium 4, Pentium D, and Pentium M brands.

The Core 2 brand was introduced on 27 July 2006, comprising the Solo (single-core), Duo (dual-core), Quad (quad-core), and in 2007, the Extreme (dual- or quad-core CPUs for enthusiasts) subbrands. Intel Core 2 processors with vPro technology (designed for businesses) include the dual-core and quad-core branches.

Models

The Core 2-branded CPUs include: "Conroe"/"Allendale" (dual-core for desktops), "Merom" (dual-core for laptops), "Merom-L" (single-core for laptops), "Kentsfield" (quad-core for desktops), and the updated variants named "Wolfdale" (dual-core for desktops), "Penryn" (dual-core for laptops), and "Yorkfield" (quad-core for desktops). (Note: For the server and workstation "Woodcrest", "Tigerton", "Harpertown" and "Dunnington" CPUs see the Xeon brand.)

Graph (discrete mathematics)

In mathematics, and more specifically in graph theory, a graph is a representation of a set of objects where some pairs of objects are connected by links. The interconnected objects are represented by mathematical abstractions called vertices (also called nodes or points), and the links that connect some pairs of vertices are called edges (also called arcs or lines). Typically, a graph is depicted in diagrammatic form as a set of dots for the vertices, joined by lines or curves for the edges. Graphs are one of the objects of study in discrete mathematics.

The edges may be directed or undirected. For example, if the vertices represent people at a party, and there is an edge between two people if they shake hands, then this is an undirected graph, because if person A shook hands with person B, then person B also shook hands with person A. In contrast, if there is an edge from person A to person B when person A knows of person B, then this graph is directed, because knowledge of someone is not necessarily a symmetric relation (that is, one person knowing another person does not necessarily imply the reverse; for example, many fans may know of a celebrity, but the celebrity is unlikely to know of all their fans). The former type of graph is called an undirected graph and the edges are called undirected edges while the latter type of graph is called a directed graph and the edges are called directed edges.
