CMM

CMM is the abbreviation of:

Capability Maturity Model

The Capability Maturity Model (CMM) is a development model created after study of data collected from organizations that contracted with the U.S. Department of Defense, who funded the research. The term "maturity" relates to the degree of formality and optimization of processes, from ad hoc practices, to formally defined steps, to managed result metrics, to active optimization of the processes.

The model's aim is to improve existing software-development processes, but it can also be applied to other processes.

Overview

The Capability Maturity Model was originally developed as a tool for objectively assessing the ability of government contractors' processes to implement a contracted software project. The model is based on the process maturity framework first described in the 1989 book Managing the Software Process by Watts Humphrey. It was later published in a report in 1993 and as a book by the same authors in 1995.

Though the model comes from the field of software development, it is also used as a general model to aid in business processes generally, and has been used extensively worldwide in government offices, commerce, industry and software-development organizations.

Materfer CMM 400-2

The CMM 400-2 is a diesel multiple unit produced by Materfer in Córdoba Province, Argentina. The units are produced in Argentina's three primary track gauges and the standard gauge variants were the first to be produced for General Urquiza Railway services in Entre Ríos Province.

Overview

The DMUs come in 1000mm, 1435mm and 1676mm track gauges, and can thus be used on any part of the network with the exception of a few tourist services. Most components are built in Argentina, with the exception of a few such as its German Knorr Bremse brakes and Swedish Scania engines. The possibility of upgrading the Scania engines to more powerful Deutz AG engines on all future and existing rolling stock is being considered.

Some of the passenger comforts in the cars include; air conditioning, pneumatic suspension, reclining seats and LED lighting. Each car has a capacity for 70 seated passengers and each trainset has a conductor's cabin on each side.

Usage

The units can be found on a variety of different urban and inter-urban services in Argentina. The first trainsets were sent to Entre Ríos Province for inter-urban services on the General Urquiza Railway's Paraná - Concepción del Uruguay line.

2015 United Nations Climate Change Conference

The 2015 United Nations Climate Change Conference, COP 21 or CMP 11 was held in Paris, France, from 30 November to 12 December 2015. It was the 21st yearly session of the Conference of the Parties (COP) to the 1992 United Nations Framework Convention on Climate Change (UNFCCC) and the 11th session of the Meeting of the Parties to the 1997 Kyoto Protocol.

The conference negotiated the Paris Agreement, a global agreement on the reduction of climate change, the text of which represented a consensus of the representatives of the 196 parties attending it. The agreement will become legally binding if joined by at least 55 countries which together represent at least 55 percent of global greenhouse emissions. Such parties will need to sign the agreement in New York between 22 April 2016 (Earth Day) and 21 April 2017, and also adopt it within their own legal systems (through ratification, acceptance, approval, or accession).

According to the organizing committee at the outset of the talks, the expected key result was an agreement to set a goal of limiting global warming to less than 2 degrees Celsius (°C) compared to pre-industrial levels. The agreement calls for zero net anthropogenic greenhouse gas emissions to be reached during the second half of the 21st century. In the adopted version of the Paris Agreement, the parties will also "pursue efforts to" limit the temperature increase to 1.5 °C. The 1.5 °C goal will require zero emissions sometime between 2030 and 2050, according to some scientists.
