Anchor

An anchor is a device, normally made of metal, used to connect a vessel to the bed of a body of water to prevent the craft from drifting due to wind or current. The word derives from Latin ancora, which itself comes from the Greek ἄγκυρα (ankura).

Anchors can either be temporary or permanent. Permanent anchors are used in the creation of a mooring, and are rarely moved; a specialist service is normally needed to move or maintain them. Vessels carry one or more temporary anchors, which may be of different designs and weights.

A sea anchor is a drogue, not in contact with the seabed, used to control a drifting vessel.

Overview

Anchors achieve holding power either by "hooking" into the seabed, or via sheer mass, or a combination of the two. Permanent moorings use large masses (commonly a block or slab of concrete) resting on the seabed. Semi-permanent mooring anchors (such as mushroom anchors) and large ship's anchors derive a significant portion of their holding power from their mass, while also hooking or embedding in the bottom. Modern anchors for smaller vessels have metal flukes which hook on to rocks on the bottom or bury themselves in soft seabed.

Handling stolen goods

Handling stolen goods is the name of a statutory offence in England and Wales and Northern Ireland. It takes place after a theft or other dishonest acquisition is completed and may be committed by a fence or other person who helps the thief to realise the value of the stolen goods. It replaces the offence of receiving stolen goods under section 33 of the Larceny Act 1916.

Handling stolen property is the name of a statutory offence in the Republic of Ireland.

England and Wales

Definition

This offence is created by section 22(1) of the Theft Act 1968 which provides:

Elements of the offence

Stolen goods

This term means property stolen anywhere, as long as the theft amounted to an offence where committed. It includes any proceeds of that property, including money for which it has been sold, and anything bought with those proceeds.

However, property which has been returned to the original owner, or otherwise lawful custody, is no longer regarded as stolen, by section 24(3). This may create difficulties, as in Haughton v. Smith.

3D modeling

In 3D computer graphics, 3D modeling (or modelling) is the process of developing a mathematical representation of any three-dimensional surface of an object (either inanimate or living) via specialized software. The product is called a 3D model. It can be displayed as a two-dimensional image through a process called 3D rendering or used in a computer simulation of physical phenomena. The model can also be physically created using 3D printing devices.

Models may be created automatically or manually. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting.

3D modeling software is a class of 3D computer graphics software used to produce 3D models. Individual programs of this class are called modeling applications or modelers.

Models

3D models represent a physical body using a collection of points in 3D space, connected by various geometric entities such as triangles, lines, curved surfaces, etc. Being a collection of data (points and other information), 3D models can be created by hand, algorithmically (procedural modeling), or scanned.
