Power system real-time thermal rating estimation
Full text linkThis Thesis describes the development and testing of a real-time rating estimation algorithm developed at Durham University within the framework of the partially Government-funded research and development project “Active network management based on component thermal properties”, involving Durham University, ScottishPower EnergyNetworks, AREVA-T&D, PB Power and Imass. The concept of real time ratings is based on the observation that power system component current carrying capacity is strongly influenced by variable environmental parameters such as air temperature or wind speed. On the contrary, the current operating practice consists of using static component ratings based on conservative assumptions. Therefore, the adoption of real-time ratings would allow latent network capacity to be unlocked with positive outcomes in a number of aspects of distribution network operation. This research is mainly focused on facilitating renewable energy connection to the distribution level, since thermal overloads are the main cause of constraints for connections at the medium and high voltage levels. Additionally its application is expected to facilitate network operation in case of thermal problems created by load growth, delaying and optimizing network reinforcements. The work aims at providing a solution to part of the problems inherent in the development of a real-time rating system, such as reducing measurements points, data uncertainty and communication failure. An extensive validation allowed a quantification of the performance of the algorithm developed, building the necessary confidence for a practical application of the system developed

Images from an Archaeological Building Recording Survey at The Brown Trout public house, Sunnybrow, Crook, Durham 2021
No full textThis collection comprises images from a Level 2 building survey of a mid-19th-century pub on the edge of a pit village, undertaken by Archaeological Services Durham University. Originally a private house, it was the Joiner's Arms into the 1970s. After a period of disuse it was refurbished and re-opened as the Brown Trout, which closed in 2019. It is a plain building, typical of its region, and retains few original feature

Proposed Business School, Elvet Waterside, Durham: archaeological recording (OASIS ID: archaeol3-359681)
No full textPhotograhic survey of a 19th-century cottage and garden walls north of Old Elvet, Durham.
This report presents the results of an archaeological recording project conducted in advance of proposed work at Elvet Waterside, Durham City. A photographic and drawn survey of Vennel Cottage and a number of garden walls has been carried out.
The works were commissioned by Durham University Estates and Facilities Directorate and conducted by Archaeological Services Durham University.
The present house probably dates from the second quarter of the 19th century but it incorporates parts of older buildings. In its present form it appears to have begun life as the south end of the large building shown on Wood's 1820 map. The east wall of that structure survives in the west side of the vennel, wall B. It was a brick building, but incorporated the thick stone wall seen in the north face of Vennel Cottage today. It is likely that this is what remains of an earlier building, of unknown date. As presently visible, the wall contains no diagnostic or dateable features. Stripping of the south face, inside Vennel Cottage, might provide more information about this structure.
The 19th-century elements of the building are of limited historical interest. Nothing remains of its documented use as a wash house and the interior has been gutted and altered for residential use.
All except the eastern walls J and K appear on the 1816 Ordnance Survey Town Plan. The oldest is the section of the vanished building in wall B, which retains some blocked openings. All of the others were clearly built as garden walls. Though there is some variety in size and form, most share the common construction of brick on the inner face and stone on the outside. This is a matter of economy rather than a desire to benefit from the thermal capacity of brickwork, which was often exploited in walled gardens. In such cases, brickwork was used on south-facing walls which receive the maximum amount of sunlight; at Elvet Waterside, brick faces appear regardless of the direction that the wall faces. There is map evidence of some small garden structures abutting some of the walls. Evidence of these was seen only in the east face of wall E and the south of wall H
Arcot, Phase 1, Cramlington, Northumberland. Post-excavation Analysis. (OASIS ID: archaeol3-368584).
No full textThis archive presents the results of analysis of an archaeological excavation conducted for a development at land off Fisher Lane (A1068), Cramlington, Northumberland. A suite of radiocarbon dates and subsequent palaeo-environmental analysis was conducted to supplement earlier data. The works were commissioned by Persimmon Homes and Bellway, and conducted by Archaeological Services Durham University. A flint flake and a Bronze Age radiocarbon date from residual material indicates that there may have been pre-Iron Age activity on the site. More definitive evidence for settlement on the site comprised two adjacent and contemporary pits, one probably an open hearth and the other a covered earth oven. Both were radiocarbon dated to the earlier Iron Age, and had been used for cooking hazelnuts and meat. A rectilinear settlement enclosed by a palisade was built on the site. Within the enclosure was a central roundhouse and two smaller roundhouses. The houses comprise surviving elements of internal wall construction slots and eaves-drip gullies. There are no indications that the enclosure or houses were rebuilt. Radiocarbon dating indicated that the settlement was occupied in the later 4th and the 3rd centuries BC, when it was abandoned. It was not subsequently reoccupied. The enclosure and houses had entrances facing to the south-west. A contemporary ditch c.100m to the north-east of the roundhouse may be an associated field boundary and indicate management of the wider landscape. There was some limited evidence for the use of cultivated cereals, including wheat, within the settlement, which may reflect this, as well as for exploitation of a local lowland oak woodland. Small-scale ironworking also took place on the site. The area was used for agriculture from the medieval period onwards, with post medieval evidence for a track associated with a 19th century planation identified, as well as a possible mine shaft
A study of the work of Dr. Felix Oswald on the Oswald-plicque collection of samian pottery, now at Durham University
Full text linkThe purpose of this thesis is to re-assess the work of Dr.Felix Oswald on the Oswald-Plicque Collection of samian pottery. The Oswald-Plicque collection was the personal samian collection of Dr.Oswald and was acquired by Professor Eric Birley for Durham University in 1950. It is now at the Museum of Archaeology, Durham. The first part of the thesis describes the history of the Collection. Its importance to samian specialists is discussed and a brief account is given of its organisation before and after arriving in Durham. The second part of the thesis analyses the Central Gaulish ware in the Collection. Dr.Oswald wrote brief notes and names on the back of each sherd indicating the potter to whom he attributed the piece. Each potter is discussed alphabetically, and an opinion is expressed as to the accuracy of Dr.Oswald's classifications. The third section of the thesis discusses the South Gaulish ware. Dr.Oswald wrote more extensive notes on the South Gaulish sherds and these have been recorded in full. The sherds have been divided on the basis of date rather than potter, and the accuracy of the dates given for each sherd is assessed. Finally the work of Dr.Oswald on the Collection is placed in the context of his times. It is concluded that many of the sherds are incorrectly attributed and that Dr.Oswald's attempt to name a style for each sherd is over ambitious and influenced by 19th century thinking. Dr.Oswald used information on figure types derived from the Collection in one of his most important works, his "Index of Figure Types on Terra Sigillata" (1936-7), and it is suggested that extreme caution should be taken when using references from this Index to unsigned work from the Oswald-Plicque Collection
