While disturbances

This paper presents a control approach for the double inverted pendulum on a cart (DIPC) by combining Hierarchical Sliding Mode Control (HSMC) and Disturbance Observer (DOB). The proposed method utilizes HSMC to ensure balance in both the pendulum angles and a cart position, while the DOB accurately estimates the system's disturbance.

Sensory disturbance is a common symptom of post-stroke. In traditional Chinese medicine (TCM), this symptom is classified as numbness (Ma Mu). While there have been many studies on the therapeutic effect of numbness in TCM, little research has been conducted on the characteristics of numbness. This study aimed to investigate the characteristics of numbness in patients with ischemic stroke in the early rehabilitation phase.

In this paper, a wireless sensor fusion module is designed and applied for an active QZS isolator for some purposes: Firstly, using wireless sensor in the active QZS isolator is to eliminate unpredictable disturbance causing by connecting wires of the wired sensors for the isolator system with almost zero stiffness is easily effected by sensitive noise [3]. Secondly, the data fusion technique embedded in wireless sensor module is to protect control system from a suddenly disabled sensor while the system is running.

Voltage sags can be symmetrical or unsymmetrical depending on the causes of the sag. At the present time, one of the most common procedures for mitigating voltage sags is by the use of dynamic voltage restorers (DVRs). By definition, a DVR is a controlled voltage source inserted between the network and a sensitive load through a booster transformer injecting voltage into the network in order to correct any disturbance affecting a sensitive load voltage. In this paper, modelling of DVR for voltage correction using MatLab software is presented.

This paper proposes ADRC in combination with Input shaping approach in which ADRC is used to reject disturbance while keeping the simplicity in design as PID controller, and Input shaping plays the role of vibration suppression. Simulations show the effectiveness of the proposed approach.

Some countries seem destined from their origin to become the battle-fields of the contending nations which environ them. Into such regions, and to their cost, neighbouring peoples come from century to century to settle their quarrels and bring to an issue the questions of supremacy which disturb their little corner of the world.

Football hooliganism periodically generates widespread political and public anxiety in a variety of European and non-European countries. In spite of the efforts made and resources invested over the past decades, football hooliganism is still perceived by politicians, policymakers, media and other actors as a disturbing social problem. Issues such as how to understand or explain hooligan behaviour continue to challenge social scientists, while at the same time instant answers and solutions are demanded from wider, non-academic audiences....

6% (compared to national average around 2%). A major consequence of the surge in urban population is the rapid growth of slums and squatter settlements. While the urban poor population is not confined to slums, these do present an aggregation of the poorest section of the urban population. Due to overcrowded, unsanitary and sub-standard dwellings, then are thus at high risk of contracting communicable diseases.

In the night of the 15th of January 1343, while the inhabitants of Naples lay wrapped in peaceful slumber, they were suddenly awakened by the bells of the three hundred churches that this thrice blessed capital contains. In the midst of the disturbance caused by so rude a call the first bought in the mind of all was that the town was on fire, or that the army of some enemy had mysteriously landed under cover of night and could put the citizens to the edge of the sword. But the doleful, intermittent sounds of all these fills, which disturbed the silence at regular and distant intervals, were...

While BLM regulations set minimum amounts for bonds, they also require bonds in an increased amount in certain circumstances and authorize BLM to require an increased bond amount when the operator poses a risk due to certain factors. First, when an operator who has failed to plug a well or reclaim lands in a timely manner that resulted in BLM making a demand on a bond in the prior 5 years applies for a new permit to drill, BLM must require a bond in an amount equal to the BLM cost estimate for plugging the well and reclaiming the disturbed...

After drilling the well, the operator may perform interim reclamation—the practice of reclaiming surfaces that were disturbed to prepare a well for drilling but that are no longer needed. For example, operators may need a 10-acre drill pad to safely drill a series of wells. However, once the wells are drilled, operators may only need 4 acres to safely service the wells over their lifetime. In this case, the operator could reseed and regrade the 6 acres of the initial pad that are no longer needed.

Sleep is a function of the brain. However, the ultimate physiological function of sleep remains enigmatic and unknown despite recent extensive research of this ubiquitous and important brain activity. Sleep intervenes in functions of somatic growth, regeneration, and memory. Sleep is important in medicine because it modulates quality of life, while its disorders provoke family pathology, disturb work routines, alter social activities, and, in general, affect the health of the individual (1).

The statistics are well known and staggering. And yet, in many countries the figures continue to worsen. Each year 500,000–600,000 women die in pregnancy and childbirth. In some parts of Sub–Saharan Africa, 1 in 6 women die in child birth, while in United States the lifetime risk is as low as 1 in 84001. HIV/AIDS statistics tell an equally disturbing story of dis- parity. In parts of Africa, over 35% of the adult population — 1 in 3 adults — is infected with HIV 2. The number of women contracting the disease is also on the rise.

Shouldn’t it be possible to conceal a house in an Alpine slope while still exploiting the wonderful views and allowing light to enter the building? Surprised that it was permissible to construct a pair of dwellings so close to the world famous thermal baths of Vals, the client seized the opportunity to develop the site, without disturbing the bath’s expansive views. The introduction of a central patio into the steep incline creates a large façade with considerable potential for window openings.

The last solution is the one of choice, if you have the machines. But many people don't and that is why one alternative is to find a shop that will help you out. If you can find such a shop it may turn out to be very easy for you to show up now and then with a few boards and quickly have them planed down, so it's worth the effort to investigate by calling around. But keep the following in mind. These shops will be busy and it is not worth their while to disturb their normal flow of...

Long-term challenges remain: continuing with structural reforms, maintaining rapid and steady economic growth and fiscal discipline, boosting employment, reining in the informal economy, and making progress with respect to EU accession. While the latter is expected to be a long and complicated process, it will remain a driving force for Turkey’s reform efforts. In addition, accelerating the reform process will be vital for a positive outlook. Recent political turmoil and upcoming local elections in 2009 could become a distraction for further reforms.

Most information about the external world enters the human mind via the visual system; when seeing and looking are impaired, important aspects of life may elude us or the world becomes disturbingly distorted. While the globe may be likened to a camera, it is the brain that constructs an image of the world. It does this by making sense of the signals it receives from the retina, in which it is helped by data stored in memory as well as data gathered through other modes of perception.

My brain is starting to play tricks on me while the second hand blindly ticks away on the old-school analog clock hanging above my head. My thoughts wander aimlessly and I often find myself wrestling with bizarre ideas that are hard to control. It’s entertaining at times but can also be disturbing. I begin to wonder which Greek god I upset. Did I do something bad in a past life that affected my Karma or is this experience nothing more than a lesson in character building? Being unemployed with nothing but time to burn, a large stack of bills, child...
