In this paper, some new developments to the packing optimization method based on the rubber band analogy are presented. This method solves packing problems by simulating the physical movements of a set of objects wrapped by a rubber band in the case of two-dimensional problems or by a rubber balloon in the case of three-dimensional problems. The objects are subjected to elastic forces applied by the rubber band to their vertices as well as reaction forces when contacts between objects occur. Based on these forces, objects translate or rotate until maximum compactness is reached. To improve the compactness further, the method is enhanced by adding two new operators: volume relaxation and temporary retraction. These two operators allow temporary volume (elastic energy) increase to get potentially better packing results. The method is implemented and applied for three-dimensional arbitrary shape objects.

Abstract General Description.—The rubber pendulum is one of two devices (Wiegand, Trans. Inst. Rubber Ind., 1, 141 (1925)) which, by employing the Joule effect, constitute rubber heat engines in that they continuously convert heat into mechanical work. In Fig. 1 is shown the original pendulum. It consists of an ordinary pendulum of slow period fitted with a rubber band, one end of which is attached to the bob; the other to the upright support. This rubber band is stretched to four or five times its original length. Behind the upright is a metal shield so arranged that when the bob has reached the extremity of its swing the rubber band is clear of the shield, during the rest of the oscillation being in its shadow. Behind the pendulum and shield is an electric heating element with a copper reflector. The pendulum is started by displacement from the center towards one or other extremity. As this is done the rubber band is increased in length. At the extremity of the oscillation the stretch band is exposed to the radiant heat from the element, the Joule effect is brought into play and the band tends to shrink, thus pulling back the bob. Directly the band moves back within the shadow of the shield it cools, relaxes, and so allows the bob to swing out to the other side. Thereupon the band is once more heated up, contracts and so repeats the oscillation, which continues as long as the heat energy is supplied. When the electric current is turned off the pendulum dies down.

Haemorrhoids are a clinical symptom of a change in the normal functional architecture of the inflamed and swollen veins known as the anal cushion. Numerous treatment opportunities are available for this communal issue, but Baron's Gum Ligation (RBL) is the utmost frequently used technique for second- and third-degree haemorrhoids because it treats hemorrhoidal disease without anaesthesia, hospitalization, minimal complications, and ooutpatient discharge is uneventful compared to conventional surgery. Purpose: We conducted this study to evaluate the effectiveness of rubber band ligation in the treatment of second- and third-degree haemorrhoids. Methodology: This prospective study was performed on 76 patients over a six-month period at the Department of General Surgery from January 2021 to June 2021 at Islam Medical College and Teaching Hospital Sialkot. Rubber rubber ligation was used in all patients. A maximum of two haemorrhoids in one session were banded, and third as needed in a check-up done two weeks later. At the end of the fourth week, post-banding assessments were made for the presence and absence of bleeding, pain, and haemorrhoidal prolapse. Results: Of the 76 patients, 60 (78.9%) were male and 16 (21.1%) were female. The M:F ratio was 5.0: 1.0. 37.85 years was the mean age of patients (range 15 to 68). The duration of symptoms in approximately 48 patients (63.2%) was less than one year old, and in 18 (23.7%) patients ranged from 1 to 3 years and 10 (13.2%) patients had symptoms for more than 4 years. Complications occurred in 23 patients, bleeding in three patients, pain in 18 patients, 2 patients have prolapsed. Conclusion: RBL is effective, safe and simple method of symptomatic treatment for 2nd and 3rd degree haemorrhoids in an outpatient setting.
